EP241217a: a likely Type II GRB with an achromatic bump at z = 4.59

Hao Zhou, Jia Ren, Chen-Wei Wang +22

EP241217a is an X-ray transient detected by the Einstein Probe (EP) lasting for about 100 seconds and without accompanying -ray detection. The optical spectroscopy reveals the r…

The radio flare and multi-wavelength afterglow of the short GRB 231117A: energy injection from a violent shell collision

G. E. Anderson, G. P. Lamb, B. P. Gompertz +64

We present the early radio detection and multi-wavelength modeling of the short gamma-ray burst (GRB) 231117A at redshift . The Australia Telescope Compact Array automatic…

Evidence for an intrinsic luminosity-decay correlation in GRB radio afterglows

S. P. R. Shilling, S. R. Oates, D. A. Kann +12

We present the discovery of a correlation, in a sample of 16 gamma-ray burst 8.5 GHz radio afterglows, between the intrinsic luminosity measured at 10 days in the rest frame, $L_{\…

Binary Neutron Star Mergers: Multi-Messenger Systematics and Prospects with Next-Generation Facilities

Nathan Steinle, Samar Safi-Harb, Matt Nicholl +2

Multi-messenger astronomy was galvanized by the detection of gravitational waves (GWs) from the binary neutron star (BNS) merger GW170817 and electromagnetic (EM) emission from the…

Late-time radio brightening and emergence of a radio jet in the changing-look AGN 1ES 1927+654

Eileen T. Meyer, Sibasish Laha, Onic I. Shuvo +32

We present multi-frequency (5-345 GHz) and multi-resolution radio observations of 1ES 1927+654, widely considered one of the most unusual and extreme changing-look active galactic…

Evidence for a luminosity-decay correlation in GRB GeV light curves

K. R. Hinds, S. R. Oates, M. Nicholl +5

Correlations between intrinsic properties of gamma-ray burst (GRB) light curves provide clues to the nature of the central engine, the jet, and a possible means to standardise GRBs…

A long-duration gamma-ray burst of dynamical origin from the nucleus of an ancient galaxy

Andrew J. Levan, Daniele B. Malesani, Benjamin P. Gompertz +29

The majority of long duration ( s) gamma-ray bursts (GRBs) are believed to arise from the collapse of massive stars \cite{Hjorth+03}, with a small proportion created from the m…

Towards an understanding of long gamma-ray burst environments through circumstellar medium population synthesis predictions

A. A. Chrimes, B. P. Gompertz, D. A. Kann +8

The temporal and spectral evolution of gamma-ray burst (GRB) afterglows can be used to infer the density and density profile of the medium through which the shock is propagating. I…

The case for a minute-long merger-driven gamma-ray burst from fast-cooling synchrotron emission

B. P. Gompertz, M. E. Ravasio, M. Nicholl +12

For decades, gamma-ray bursts (GRBs) have been broadly divided into `long'- and `short'-duration bursts, lasting more or less than 2s, respectively. However, this dichotomy does no…

A Kilonova Following a Long-Duration Gamma-Ray Burst at 350 Mpc

J. C. Rastinejad, B. P. Gompertz, A. J. Levan +32

Here, we report the discovery of a kilonova associated with the nearby (350 Mpc) minute-duration GRB 211211A. In tandem with deep optical limits that rule out the presence of an ac…

Simultaneous view of the FRB~180301 with FAST and NICER during a bursting phase

Sibasish Laha, George Younes, Zorawar Wadiasingh +16

FRB180301 is one of the most actively repeating fast radio bursts (FRBs) which has shown polarization angle changes in its radio burst emission, an indication for their likely orig…

Observation of inverse Compton emission from a long -ray burst

V. A. Acciari, S. Ansoldi, L. A. Antonelli +301

Long-duration gamma-ray bursts (GRBs) originate from ultra-relativistic jets launched from the collapsing cores of dying massive stars. They are characterised by an initial phase o…

The Tidal Disruption Event AT 2018hyz I: Double-peaked emission lines and a flat Balmer decrement

P. Short, M. Nicholl, A. Lawrence +28

We present results from spectroscopic observations of AT 2018hyz, a transient discovered by the ASAS-SN survey at an absolute magnitude of mag, in the nucleus of a…

Be X-ray binaries in the SMC as indicators of mass transfer efficiency

Serena Vinciguerra, Coenraad J. Neijssel, Alejandro Vigna-Gómez +7

Be X-ray binaries (BeXRBs) consist of rapidly rotating Be stars with neutron star companions accreting from the circumstellar emission disk. We compare the observed population of B…

GRB171010A / SN2017htp: a GRB-SN at z=0.33

A. Melandri, D. B. Malesani, L. Izzo +41

The number of supernovae known to be connected with long-duration gamma-ray bursts is increasing and the link between these events is no longer exclusively found at low redshift ($…
