Research Focus 研究方向简介

My research focuses on high-energy time-domain and multi-messenger astrophysics, especially GRBs, FRBs, and gravitational-wave electromagnetic counterparts, combining data analysis, physical modeling, and space instrumentation.

我的研究聚焦于高能时域与多信使天体物理,重点关注伽马射线暴、快速射电暴与引力波电磁对应体,融合观测数据分析、物理模型构建与空间探测器研制。

What happens when a dying star collapses, or two neutron stars spiral into each other at nearly the speed of light? The answer is a gamma-ray burst (GRB)—one of the most powerful explosions in the universe. Our group studies these extreme events across the electromagnetic spectrum, from gamma-rays and X-rays captured by space telescopes such as Fermi, Swift, and the Einstein Probe, to optical and infrared data from global ground-based facilities.

We combine data-driven analysis with physical modeling to address major open questions: what powers these explosions, how heavy elements form in compact-object mergers, and whether we can capture distinct signatures of newborn neutron stars. Recent results have helped refine GRB classification and identify evidence for magnetar engines in merger-related events.

Beyond analysis, we also build hardware. Our student-led GRID (Gamma-Ray Integrated Detectors) CubeSat program, developed jointly with Tsinghua University, has launched multiple missions and detected dozens of GRBs, offering end-to-end training from detector design to on-orbit operations.

当一颗垂死的大质量恒星坍缩,或两颗中子星以接近光速相互旋进时,会发生什么?答案是伽马射线暴(GRB)——极端高能暂现事件之一。我们利用费米、雨燕、爱因斯坦探针等空间望远镜的伽马射线和 X 射线数据,结合全球地面光学与红外观测,开展全波段研究。

我们将数据分析与物理建模相结合,聚焦关键问题:爆发能量来源、致密并合中重元素形成机制,以及新生中子星的可观测特征。近年来的工作推动了 GRB 分类的完善,并为并合相关事件中的磁星引擎提供了证据链。

在数据分析之外,我们也进行仪器研制。由学生主导的 GRID(伽马射线集成探测器)立方星计划与清华大学联合研发,已多次发射并探测到数十个 GRB,让学生获得从探测器设计到在轨运行的全流程实践经验。

2026-11-06张彬彬教授领衔项目荣获2025年度江苏省自然科学奖一等奖

Prof. Zhang Binbin-led Project Wins First Prize of the 2025 Jiangsu Provincial Natural Science Award
2026年11月6日,江苏省科技奖励大会在南京召开。由张彬彬教授团队牵头,联合中国科学院紫金山天文台、国家天文台、广西大学、云南天文台等单位共同完成的"伽马射线暴的起源和发生机制"项目,荣获2025年度江苏省自然科学奖一等奖。
On November 6, 2026, the Jiangsu Provincial Science and Technology Awards Conference was held in Nanjing. The project "Origin and Physical Mechanisms of Gamma-Ray Bursts", led by Prof. Zhang Binbin's team in collaboration with the Purple Mountain Observatory (Chinese Academy of Sciences), the National Astronomical Observatories of China, Guangxi University, and Yunnan Observatories, was awarded the First Prize of the 2025 Jiangsu Provincial Natural Science Award.
该项目依托空间高能观测与多波段后随观测,通过数据分析与物理建模,构建了多波段物理起源判据体系,突破了"长暴源于坍缩、短暴源于并合"的传统认知,揭示了磁陀星巨耀发这一第三类起源通道;深入解析了喷流结构与辐射机制,为阐明伽马射线暴的发生机制提供了关键观测约束。相关成果发表于《自然》等国际顶级学术期刊,有力推动了多信使天文学的发展。

Leveraging space-based high-energy observations and multi-wavelength follow-up observations, the project established a multi-wavelength classification scheme for the physical origins of gamma-ray bursts (GRBs) through data analysis and physical modeling. It broke through the traditional dichotomy that "long GRBs originate from collapsars and short GRBs from mergers", revealing magnetar giant flares as a third origin channel. The project also provided an in-depth analysis of jet structures and radiation mechanisms, offering key observational constraints for understanding the physical mechanisms of GRBs. The related results have been published in top-tier international journals such as Nature, significantly advancing the development of multi-messenger astronomy.

A Shared Rhythm in Short Gamma-Ray Bursts Points to Magnetar Giant Flares

Two high-energy explosions recorded nearly three decades apart may share a similar oscillatory “clock.” By reanalyzing the short gamma-ray burst GRB 910711 and comparing it with the extragalactic magnetar giant flare GRB 200415A, researchers found not only similar rapid brightness variations but also a harmonic-like structure organized around approximately 360 Hz. Together with spectral and energetic evidence, these findings support a possible magnetar giant flare origin for GRB 910711, offering a new clue to the true nature of these fleeting explosions.

On October 28, 2026,our group together with collaborators from Department of Physics and Kavli Institute for Astrophysics and Space Research at Massachusetts Institute of Technology and other institutions, published their findings in Science Advances in a research article entitled “Harmonic brightness oscillations point to magnetar giant flares in rare short gamma-ray bursts.”

短伽马射线暴中的共同节律指向磁陀星巨耀发

两次相隔近三十年的高能爆发,可能共享相似的振荡“时钟”。研究人员重新分析短伽马射线暴GRB 910711,并将其与河外磁陀星巨耀发GRB 200415A比较,发现两者不仅具有相似的快速光变,还呈现出围绕约360赫兹展开的类谐波结构。结合能谱和能量分析,这些证据支持GRB 910711可能源于磁陀星巨耀发,为辨认这类短暂爆发的真实起源提供了新线索。

2026年10月28日,我们研究小组联合麻省理工学院物理系及卡夫里天体物理与空间研究所等单位,在《科学进展》(Science Advances)发表题为“Harmonic brightness oscillations point to magnetar giant flares in rare short gamma-ray bursts”的研究论文。

Minutes-long Soft X-ray Prompt Emission from a Compact Object Merger

天关卫星发现致密天体并合的分钟级软X射线瞬时辐射

When two neutron stars collide and merge, how long can we see their high-energy emission? Until now, the familiar signature has been a short gamma-ray burst lasting less than two seconds. A new discovery by the Einstein Probe (EP, also known as Tianguan) shows, however, that the end of the gamma-ray burst does not mean this cosmic explosion is over.

Recently, Professor Bin-Bin Zhang of the School of Astronomy and Space Science, Nanjing University, together with collaborators from the EP collaboration in China and abroad, carried out an in-depth study of EP250704a/GRB 250704B, a high-energy burst produced by a compact object merger. The burst was captured simultaneously by EP, the China–France SVOM satellite and the Insight-HXMT satellite, which monitored it in full in soft X-rays and gamma rays respectively, offering a rare opportunity to trace the early evolution of the emission from a compact object merger. The study finds that the short gamma-ray burst, which lasted less than half a second, was followed by a “hidden” episode of soft X-ray activity lasting nearly ten minutes, indicating that the merger remnant continued to release substantial energy for a considerable time. This implies that compact star mergers—important sources of gravitational waves—can also appear as fast X-ray transients lasting several minutes, opening a new observational window for the search for electromagnetic counterparts of gravitational-wave events and for multi-messenger astronomy. The results were published in the journal Science Bulletin under the title “Minutes-long soft X-ray prompt emission from a compact object merger”. The work was jointly led by Nanjing University, the University of Rome “Tor Vergata”, the University of Hong Kong and the National Astronomical Observatories of the Chinese Academy of Sciences, with Nanjing University as the first corresponding-author institution.

两颗中子星碰撞并合时,我们究竟能看到多久的高能辐射?过去,人们熟悉的是持续不到两秒的短伽马射线暴。而天关卫星(Einstein Probe,EP)的一个新发现显示,伽马射线暴结束,并不意味着这场宇宙高能爆发已经落幕。

近日,南京大学天文与空间科学学院张彬彬教授与天关卫星合作组的国内外合作者一道,对一例来自致密天体并合产生的高能爆发EP250704a/GRB 250704B开展了深入研究。此次爆发被天关卫星、中法天文卫星(SVOM)和慧眼卫星(Insight-HXMT)同时捕捉,分别在软X射线和伽马射线能段被完整监测,为研究人员追踪致密天体并合辐射的早期演化提供了难得的机会。研究发现,持续不足半秒的短伽马射线暴之后还存在长达近十分钟的“隐藏”软X射线活动,表明并合产物仍在相当长的一段时间内持续释放大量能量。这一发现意味着,作为重要引力波源的致密星并合还可能表现为持续数分钟的快速X射线暂现源事件,这为寻找引力波的电磁对应体和开展多信使天文学研究提供了新的观测窗口。相关成果以“Minutes-long soft X-ray prompt emission from a compact object merger”为题近日发表于国际学术期刊《科学通报》(Science Bulletin)。这项工作由南京大学、罗马第二大学、香港大学和国家天文台共同牵头完成,南京大学为论文的第一通讯作者单位。

Explosions in the Empty: A Survey of Transients in Local Void Galaxies

Our team conducted the first systematic census of astrophysical transients—supernovae (SNe), gamma-ray bursts (GRBs), and fast radio bursts (FRBs)—in void versus non-void galaxies within the local Universe. Using multiwavelength data spanning ~26,000 void galaxies and ~79,000 non-void galaxies, we find that core-collapse SNe are significantly overrepresented in voids (~57% of all void SNe versus ~40% outside), reflecting the younger, more actively star-forming stellar populations in these underdense environments. In contrast, Type Ia SNe are suppressed in voids, consistent with a deficit of old stellar populations. Notably, we identify one short GRB (GRB 080121) hosted by a void galaxy, demonstrating that compact binary mergers can occur even in the most isolated cosmic environments. No FRBs are found within voids in our sample. These results establish that large-scale cosmic structure leaves a measurable imprint on the demographics of stellar death across the nearby Universe. The paper is led by my Ph.D. student Suo-Ning Wang.

Millisecond Periodic Signals Discovered Again in a Short Gamma-Ray Burst Sample

Our team discovered the second statistically significant millisecond-timescale periodic signal—a coherent oscillation at approximately 1100 Hz (corresponding to a period of ~0.9 milliseconds) in short gamma-ray burst GRB 960616, which occurred in 1996. Its physical properties are highly consistent with the millisecond-scale periodic signal first discovered in GRB 230307A, further supporting the physical picture that the central engines of short gamma-ray bursts harbor rapidly spinning millisecond magnetars. The paper is led by my Ph.D. student Runchao Chen.

Evidence for a Millisecond Magnetar Periodicity in a Gamma-Ray Burst, Published in Nature Astronomy

Our Ph.D. student, Runchao Chen, published a first-author paper entitled “Evidence for a brief appearance of gamma-ray periodicity after a compact star merger” in Nature Astronomy. In this paper, we detected a brief but highly coherent oscillation in the GRB designated GRB 230307A on 7 March 2023. The signal, spinning nearly a thousand times per second, points to the birth of a “millisecond magnetar”—a rapidly rotating neutron star with an ultra-strong magnetic field.

Spectral Hardening Marks the Emergence of a GRB Afterglow

Einstein Probe (EP) and NASA’s Fermi/GBM have caught GRB 250404A (EP250404a) in the act of changing personality—from its prompt gamma-ray flash to the steadier external-shock afterglow. In a new Letter led by Yi-Han Iris Yin with Prof. Bin-Bin Zhang’s group at Nanjing University, the team follows an unbroken 600-s X-ray light curve whose spectrum first softens, then hardens dramatically, and finally levels off at a slope of ≈ –2. Broadband optical/near-IR data modelled with forward- and reverse-shock components confirm that this “soft-hard-flat” trend pinpoints the exact moment the relativistic jet slams into its environment and the afterglow takes over.

The hardening implies the prompt soft-X-ray phase actually lasted about 300 s—over three times longer than its γ-ray T90—revealing how long-duration fast X-ray transients can hide prompt emission below 10 keV. The authors propose this spectral fingerprint as a practical flag for identifying GRBs in EP’s growing catalogue of fast X-ray transients, even when γ-ray coverage or a clear temporal break is absent.

The study, co-authored by more than 60 collaborators, is now available on arXiv (2506.00435).

Direct Evidence of a Magnetar in the Central Engine of a Peculiar Long Gamma-Ray Burst

Einstein Probe’s Pathfinder mission LEIA and GECAM mission have recently discovered direct evidence of a magnetic neutron star serving as the central engine in a peculiar long gamma-ray burst GRB 230307A. This finding suggests that long gamma-ray bursts may originate from a compact binary merger involving a magnetized neutron star, which rotates rapidly and possesses an extremely strong magnetic field. The research has been published in National Science Review. My Ph.D. student, Jun Yang, is the co-first-author of the paper.

“Bridging the Gap”

In September 2024, our team reported on GRB 230812B, a remarkable gamma-ray burst detected by the Gamma-Ray Integrated Detectors (GRID) constellation mission. The paper, co-authored by Chenyu Wang, a Tsinghua University student, including myself as the corresponding author, is titled “Bridging the Gap: GRB 230812B—A Three-Second Supernova-Associated Burst Detected by the GRID Mission.” This burst, with a duration of just 3 seconds, challenges the conventional categorization of GRBs, as it originates from a massive star collapse despite its short duration. Our analysis, utilizing a time-evolving synchrotron model, sheds light on this rare phenomenon.

“One Fits All: A Unified Synchrotron Model Explains GRBs with FRED-shape Pulses”

A new study led by Ph.D. student Zhenyu Yan has been published in ApJ. The paper introduces a synchrotron model that simplifies the analysis of gamma-ray bursts (GRBs) by using a single set of parameters to explain both their spectral and temporal evolution. This approach sheds light on the GRB light curve’s phases and peak energy changes, suggesting an expanding emission region as the underlying mechanism. The findings offer a fresh perspective on GRB analysis and could guide future astrophysical research.
