SN 2021gno: a Calcium-rich transient with double-peaked light curves
K. Ertini, G. Folatelli, L. Martinez +52
We present extensive ultraviolet (UV) and optical photometric and optical spectroscopic follow-up of supernova (SN)~2021gno by the "Precision Observations of Infant Supernova Explo…
Early Spectroscopy and Dense Circumstellar Medium Interaction in SN 2023ixf
K. Azalee Bostroem, Jeniveve Pearson, Manisha Shrestha +53
We present the optical spectroscopic evolution of SN~2023ixf seen in sub-night cadence spectra from 1.18 to 14 days after explosion. We identify high-ionization emission features,…
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…
The rise and fall of the iron-strong nuclear transient PS16dtm
T. Petrushevska, G. Leloudas, D. Ilic +30
Thanks to the advent of large-scale optical surveys, a diverse set of flares from the nuclear regions of galaxies has recently been discovered. These include the disruption of star…
Weak Mass Loss from the Red Supergiant Progenitor of the Type II SN 2021yja
Griffin Hosseinzadeh, Charles D. Kilpatrick, Yize Dong +56
We present high-cadence optical, ultraviolet (UV), and near-infrared data of the nearby ( Mpc) Type II supernova (SN) 2021yja. Many Type II SNe show signs of interactio…
SN 2018bsz: significant dust formation in a nearby superluminous supernova
T. -W. Chen, S. J. Brennan, R. Wesson +41
We investigate the thermal emission and the extinction from dust associated with the nearby (z = 0.0267) superluminous supernova (SLSN) 2018bsz. Our dataset combines daily-cadence,…
