A very luminous jet from the disruption of a star by a massive black hole
Igor Andreoni, Michael W. Coughlin, Daniel A. Perley +78
Tidal disruption events (TDEs) are bursts of electromagnetic energy released when supermassive black holes (SMBHs) at the centers of galaxies violently disrupt a star that passes t…
Dissecting the interstellar medium of a z=6.3 galaxy: X-shooter spectroscopy and HST imaging of the afterglow and environment of the Swift GRB 210905A
A. Saccardi, S. D. Vergani, A. De Cia +35
The study of the properties of galaxies in the first billion years after the Big Bang is one of the major topic of current astrophysics. Optical/near-infrared spectroscopy of the a…
Chasing Super-Massive Black Hole merging events with and LISA
L. Piro, M. Colpi, J. Aird +15
The European Space Agency is studying two large-class missions bound to operate in the decade of the 30s, and aiming at investigating the most energetic and violent phenomena in th…
Finding high-redshift gamma-ray bursts in tandem near-infrared and optical surveys
S. Campana, G. Ghirlanda, R. Salvaterra +8
The race for the most distant object in the Universe has been played by long-duration gamma-ray bursts (GRBs), star-forming galaxies and quasars. GRBs took a temporary lead with th…
Short GRB Host Galaxies I: Photometric and Spectroscopic Catalogs, Host Associations, and Galactocentric Offsets
Wen-fai Fong, Anya E. Nugent, Yuxin Dong +25
We present a comprehensive optical and near-infrared census of the fields of 90 short gamma-ray bursts (GRBs) discovered in 2005-2021, constituting all short GRBs for which host ga…
Short GRB Host Galaxies. II. A Legacy Sample of Redshifts, Stellar Population Properties, and Implications for their Neutron Star Merger Origins
Anya E. Nugent, Wen-fai Fong, Yuxin Dong +14
We present the stellar population properties of 69 short gamma-ray burst (GRB) host galaxies, representing the largest uniformly-modeled sample to-date. Using the Prospector stella…
SkyHopper mission science case I: Identification of high redshift Gamma-Ray Bursts through space-based near-infrared afterglow observations
Matt Thomas, Michele Trenti, Jochen Greiner +9
Long-duration gamma-ray burst (GRB) afterglow observations offer cutting-edge opportunities to characterise the star formation history of the Universe back to the epoch of reionisa…
Where are the magnetar binary companions? Candidates from a comparison with binary population synthesis predictions
A. A. Chrimes, A. J. Levan, A. S. Fruchter +7
It is well established that magnetars are neutron stars with extreme magnetic fields and young ages, but the evolutionary pathways to their creation are still uncertain. Since most…
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…
New candidates for magnetar counterparts from a deep search with the Hubble Space Telescope
A. A. Chrimes, A. J. Levan, A. S. Fruchter +5
We report the discovery of six new magnetar counterpart candidates from deep near-infrared Hubble Space Telescope imaging. The new candidates are among a sample of nineteen magneta…
A blast from the infant Universe: the very high-z GRB 210905A
A. Rossi, D. D. Frederiks, D. A. Kann +52
We present a detailed follow-up of the very energetic GRB 210905A at a high redshift of z = 6.312 and its luminous X-ray and optical afterglow. We obtained a photometric and spectr…
Inhomogeneous Jets from Neutron Star Mergers: One Jet to Rule them all
Gavin P Lamb, Lorenzo Nativi, Stephan Rosswog +4
Using the resultant profiles from 3D hydrodynamic simulations of relativistic jets interacting with neutron star merger wind ejecta, we show how the inhomogeneity of energy and vel…
