One year of broadband radio monitoring of the enigmatic transient GRB 250702B reveals the evolution of the relativistic jet
A. J. Goodwin, James C. A. Miller-Jones, Itai Sfaradi +18
We present an extensive radio monitoring campaign of the unique extragalactic transient GRB 250702B, with observations spanning 0.65-233 GHz from 6-356 d (observer frame) post-disc…
X-rays breaking out of pre-explosion ejecta mark a supernova's first light
Weimin Yuan, Qiu-Ju Huang, Jin-Ping Zhu +130
Massive stars die as core-collapse supernovae, whose optical light emerges days after the implosion. Theory predicts that the initial collapse-driven shock, upon breaking through t…
A search for successful and choked jets in nearby broad-lined Type Ic supernovae
Tanner O'Dwyer, Alessandra Corsi, Sheng Yang +16
The observational link between long gamma-ray bursts (GRBs) and broad-lined stripped-envelope core-collapse supernovae (SNe Ic-BL) is well established. Significant progress has bee…
Continued radio observations of the persistent radio source associated with FRB20190520B provides insights into its origin
Arvind Balasubramanian, Mohit Bhardwaj, Shriharsh P. Tendulkar
Follow-up studies of persistent emission from fast radio burst (FRB) sources are critical for understanding their elusive emission mechanisms and the nature of their progenitors. T…
Constraining the Origin of FRB 20121102A's Persistent Radio Source with Long-Term Radio Observations
Mohit Bhardwaj, Arvind Balasubramanian, Yasha Kaushal +1
The persistent radio source (PRS) associated with FRB 20121102A, the first precisely localized repeating fast radio burst (FRB), provides key constraints on both its local environm…
CHIME/FRB Outriggers: KKO Station System and Commissioning Results
Adam E. Lanman, Shion Andrew, Mattias Lazda +43
Localizing fast radio bursts (FRBs) to their host galaxies is an essential step to better understanding their origins and using them as cosmic probes. The CHIME/FRB Outrigger progr…
Localisation of Gamma Ray Bursts using AstroSat Mass Model
Divita Saraogi, J Venkata Aditya, Varun Bhalerao +12
The Cadmium Zinc Telluride Imager (CZTI) aboard AstroSat has good sensitivity to Gamma Ray Bursts (GRBs), with close to 600 detections including about 50 discoveries undetected by…
Collapsars as Sites of r-process Nucleosynthesis: Systematic Near-Infrared Follow-up of Type Ic-BL Supernovae
Shreya Anand, Jennifer Barnes, Sheng Yang +41
One of the open questions following the discovery of GW170817 is whether neutron star mergers are the only astrophysical sites capable of producing -process elements. Simulation…
A search for relativistic ejecta in a sample of ZTF broad-lined Type Ic supernovae
Alessandra Corsi, Anna Y. Q. Ho, S. Bradley Cenko +23
The dividing line between gamma-ray bursts (GRBs) and ordinary stripped-envelope core-collapse supernovae (SNe) is yet to be fully understood. Observationally mapping the variety o…
AT2019wxt: An ultra-stripped supernova candidate discovered in electromagnetic follow-up of a gravitational wave trigger
Hinna Shivkumar, Amruta D. Jaodand, Arvind Balasubramanian +13
We present optical, radio and X-ray observations of a rapidly-evolving transient AT2019wxt (PS19hgw), discovered during the search for an electromagnetic (EM) counterpart to the gr…
GW170817 4.5 years after merger: Dynamical ejecta afterglow constraints
Arvind Balasubramanian, Alessandra Corsi, Kunal P. Mooley +6
GW170817 is the first binary neutron star (NS) merger detected in gravitational waves (GWs) and photons, and so far remains the only GW event of its class with a definitive electro…
Predicting the near-wall region of turbulence through convolutional neural networks
A. G. Balasubramanian, L. Guastoni, A. Güemes +5
Modelling the near-wall region of wall-bounded turbulent flows is a widespread practice to reduce the computational cost of large-eddy simulations (LESs) at high Reynolds number. A…
The AstroSat Mass Model: Imaging and Flux studies of off-axis sources with CZTI
Sujay Mate, Tanmoy Chattopadhyay, Varun Bhalerao +11
The Cadmium Zinc Telluride Imager (CZTI) on AstroSat is a hard X-ray coded-aperture mask instrument with a primary field of view of 4.6 x 4.6 degrees (FWHM). The instrument collima…
