The Type Ia Supernova 2021hem: A 2003fg-like Event in an Apparently Hostless Environment

Subhash Bose, M. D. Stritzinger, A. Malmgaard +25

We report observations of Type Ia SN 2021hem, located in an apparently hostless environment. With a peak absolute B-band magnitude of -19.96 mag, and a lack of secondary maximum in…

Emergence hour-by-hour of -process features in the kilonova AT2017gfo

Albert Sneppen, Darach Watson, Rasmus Damgaard +4

The spectral features in the optical/near-infrared counterparts of neutron star mergers (kilonovae, KNe), evolve dramatically on hour timescales. To examine the spectral evolution…

The fast transient AT 2023clx in the nearby LINER galaxy NGC 3799 as a tidal disruption of a very low-mass star

P. Charalampopoulos, R. Kotak, T. Wevers +30

We present an extensive analysis of the optical and UV properties of AT2023clx, the closest TDE to date, that occurred in the nucleus of the interacting LINER galaxy, NGC3799 (z=0.…

Discovery of a 760 nm P Cygni line in AT2017gfo: Identification of yttrium in the kilonova photosphere

Albert Sneppen, Darach Watson

Neutron star mergers are believed to be a major cosmological source of rapid neutron-capture elements. The kilonovae associated with neutron star mergers have to date yielded only…
