Luminous Fast Blue Optical Transients in the 2040s
A. A. Chrimes, N. Sarin, D. Coppejans +6
Luminous Fast Blue Optical Transients (LFBOTs) are a class of extragalactic transient of uncertain origin. Several hypotheses have been put forward which could feasibly be consiste…
AT 2018cow at ~5 years: additional evidence for a tidal disruption origin
Anne Inkenhaag, Andrew J. Levan, Andrew Mummery +1
The Luminous Fast Blue Optical Transient (LFBOT) AT 2018cow is the prototype of its class with an extensive set of multi-wavelength observations. Despite a rich data set there is,…
First joint absorption and T-based metallicity measured in a GRB host galaxy at using JWST/NIRSpec
Anne Inkenhaag, Patricia Schady, Phil Wiseman +20
We present the first gamma-ray burst (GRB) host galaxy with a measured absorption line and electron temperature (T) based metallicity, using the temperature sensitive [OIII]…
First IFU observations of two GRB host galaxies at cosmic noon with JWST/NIRSpec
B. Topçu, P. Schady, S. Wuyts +16
Long gamma-ray bursts (GRBs) serve as powerful probes of distant galaxies. Their luminous afterglow pinpoints galaxies independent of luminosity, in contrast to most flux-limited s…
A study on late time UV-emission in core collapse supernovae and the implications for the peculiar transient AT2018cow
Anne Inkenhaag, Peter G. Jonker, Andrew J. Levan +4
Over time, core-collapse supernova (CCSN) spectra become redder due to dust formation and cooling of the SN ejecta. A UV detection of a CCSN at late times thus indicates an additio…
Redshifts of candidate host galaxies of four fast X-ray transients using VLT/MUSE
Anne Inkenhaag, Peter G. Jonker, Andrew J. Levan +3
Fast X-ray transients (FXTs) are X-ray flares lasting minutes to hours. Multi-wavelength counterparts to these FXTs have been proven hard to find. As a result distance measurements…
XMM-Newton-discovered Fast X-ray Transients: Host galaxies and limits on contemporaneous detections of optical counterparts
D. Eappachen, P. G. Jonker, J. Quirola-Vásquez +18
Extragalactic fast X-ray transients (FXTs) are a class of soft (0.3-10 keV) X-ray transients lasting a few hundred seconds to several hours. Several progenitor mechanisms have been…
Late time HST UV and optical observations of AT~2018cow: extracting a cow from its background
Anne Inkenhaag, Peter G. Jonker, Andrew J. Levan +4
The bright, blue, rapidly evolving AT2018cow is a well-studied peculiar extragalactic transient. Despite an abundance of multi-wavelength data, there still is no consensus on the n…
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…
Panning for gold, but finding helium: discovery of the ultra-stripped supernova SN2019wxt from gravitational-wave follow-up observations
I. Agudo, L. Amati, T. An +96
We present the results from multi-wavelength observations of a transient discovered during the follow-up of S191213g, a gravitational wave (GW) event reported by the LIGO-Virgo Col…
Probing for the host galaxies of the fast X-ray transients XRT 000519 and XRT 110103
D. Eappachen, P. G. Jonker, M. Fraser +13
Over the past few years, 30 extragalactic fast X-ray transients (FXRTs) have been discovered, mainly in Chandra and XMM-Newton data. Their nature remains unclear, with propos…
Host Galaxy Line Diagnostics for the Candidate Tidal Disruption Events XMMSL1 J111527.3+180638 and PTF09axc
Anne Inkenhaag, Peter G. Jonker, Giacomo Cannizzaro +2
We present results of our analysis of spectra of the host galaxies of the candidate Tidal Disruption Events (TDEs) XMMSL1 J111527.3+180638 and PTF09axc to determine the nature of t…
