Stellar Wind-Blown Bubbles as Environments for Late-Time Rebrightening of Gamma-Ray Burst Afterglows
Jia Ren, Xiao-Yan Li, Yun Wang +5
We presented the multi-wavelength afterglow fitting results for three events that exhibit late afterglow rebrightening behavior: EP240414a (), GRB 240529A (), and…
A Comprehensive Analysis of Text-Book-Version Afterglow Light curves of Gamma-Ray Bursts and Implication for Universal Radiation Physics of Baryonic Jets
Lu-Lu Zhang, Shu-Qing Zhong, Li-Ping Xin +1
The standard external shock model in the thin-shell scenario predicts an onset bump in the early optical afterglow light curves of gamma-ray bursts (GRBs). We collect such a textbo…
The Interaction between AGN and Starburst Activity in the Circumnuclear Region of NGC 7469 as Viewed with JWST
Lulu Zhang, Luis C. Ho
We combine mid-infrared diagnostics obtained from integral-field unit observations taken with MIRI/MRS on JWST with cold molecular gas information derived from ALMA observations of…
Very-High-Energy Gamma-Ray Afterglows of GRB 201015A and GRB 201216C
Lu-Lu Zhang, Jia Ren, Yun Wang +1
Gamma-ray bursts (GRBs) 201015A and 201216C are valuable cases with detection of very high energy (VHE) gamma-ray afterglows. By analysing their prompt emission data, we find that…
Hard TeV Gamma-Ray Afterglows of Nearby GRB 190829A as a Tentative Signature of Ultra-High-Energy Cosmic Rays Accelerated in Gamma-Ray Burst Jets
Jian-Kun Huang, Xiao-Li Huang, Ji-Gui Cheng +3
The observed hard TeV gamma-ray spectrum of the nearby gamma-ray burst (GRB) 190829A may challenge the conventional leptonic GRB afterglow model. It has been proposed that an ultra…
Prompt-to-afterglow transition of optical emission in a long gamma-ray burst consistent with a fireball
Liping Xin, Xuhui Han, Huali Li +19
Long gamma-ray bursts (GRBs), which signify the end-life collapsing of very massive stars, are produced by extremely relativistic jets colliding into circumstellar medium. Huge ene…
Photometric and Spectroscopic Observations of GRB 210104A: Bright Reverse shock Emission and Dense Circumburst Environment
Lu-Lu Zhang, Li-Ping Xin, Jing Wang +6
Early afterglow observations of gamma-ray bursts (GRBs) are valuable for exploring the properties of their jets and ambient medium. We report our photometric and spectroscopic obse…
The Contribution of Evolved Stars to PAH Heating and Implications for Estimating Star Formation Rates
Lulu Zhang, Luis C. Ho
Emission from polycyclic aromatic hydrocarbons (PAHs) is a promising tool for estimating star formation rate (SFR) in galaxies, but the origin of its sources of excitation, which i…
Estimating Molecular Gas Content in Galaxies from PAH Emission
Lulu Zhang, Luis C. Ho
Emission from polycyclic aromatic hydrocarbons (PAHs), a commonly used indicator of star formation activity in galaxies, also has the potential to serve as an effective empirical t…
Evidence that Shocks Destroy Small PAH Molecules in Low-luminosity Active Galactic Nuclei
Lulu Zhang, Luis C. Ho, Aigen Li
We combined mapping-mode mid-infrared Spitzer spectra with complementary infrared imaging to perform a spatially resolved study of polycyclic aromatic hydrocarbons (PAHs) emission…
The Possibility of Modeling the Very High Energy Afterglow of GRB 221009A in a Wind Environment
Jia Ren, Yun Wang, Lu-Lu Zhang +1
In this paper, we model the dynamics and radiation physics of the rarity event GRB 221009A afterglow in detail. By introducing a top-hat jet that propagates in an environment domin…
Nearby SN-Associated GRB~190829A: Environment, Jet Structure, and VHE Gamma-Ray Afterglows
Zhang Lu-Lu, Ren Jia, Huang Xiao-Li +3
We present a self-consistent paradigm for interpreting the striking features of nearby low-luminosity GRB~190829A. Its prompt gamma-ray lightcurve has two separated pulses. We prop…
Constraining the Jet Launching Time of GRB 170817A by Utilizing the Baryon Loading
Jia Ren, Da-Bin Lin, Lu-lu Zhang +4
The observed delay of GRB 170817A relative to GW170817 carries significant information about gamma-ray burst (GRB) physics and is subject to intense debate. In this letter, we put…

Le Zou, Zi-Min Zhou, Lang Xie +5
Gamma-ray burst (GRB) central engines and jet production mechanisms are still open questions. Assuming that the shallow decay segments of canonical X-ray afterglow lightcurves of {…
