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]$λ…
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…
