Close, bright and boxy: the superluminous SN 2018hti

A. Fiore, S. Benetti, M. Nicholl +37

SN 2018hti was a very nearby (z=0.0614) superluminous supernova with an exceedingly bright absolute magnitude of -21.7 mag in r-band at maximum. The densely sampled pre-maximum lig…

Circumstellar Interaction Powers the Light Curves of Luminous Rapidly Evolving Optical Transients

C. Pellegrino, D. A. Howell, J. Vinkó +16

Rapidly evolving transients, or objects that rise and fade in brightness on timescales two to three times shorter than those of typical Type Ia or Type II supernovae (SNe), have un…

Circumstellar Medium Constraints on the Environment of Two Nearby Type Ia Supernovae: SN 2017cbv and SN 2020nlb

D. J. Sand, S. K. Sarbadhicary, C. Pellegrino +23

We present deep Chandra X-ray observations of two nearby Type Ia supernovae, SN 2017cbv and SN 2020nlb, which reveal no X-ray emission down to a luminosity 5.3$\time…

SN 2020cpg: an energetic link between type IIb and Ib supernovae

K. Medler, P. A. Mazzali, J. Teffs +18

Stripped-envelope supernovae (SE-SNe) show a wide variety of photometric and spectroscopic properties. This is due to the different potential formation channels and the stripping m…

Near-IR Type Ia SN distances: host galaxy extinction and mass-step corrections revisited

J. Johansson, S. B. Cenko, O. D. Fox +17

We present optical and near-infrared (NIR, -band) observations of 42 Type Ia supernovae (SNe Ia) discovered by the untargeted intermediate Palomar Transient Factory (iPTF) sur…

The double-peaked type Ic Supernova 2019cad: another SN 2005bf-like object

C. P. Gutiérrez, M. C. Bersten, M. Orellana +23

We present the photometric and spectroscopic evolution of supernova (SN) 2019cad during the first days from explosion. Based on the light curve morphology, we find that S…

AT 2019qyl in NGC 300: Internal Collisions in the Early Outflow from a Very Fast Nova in a Symbiotic Binary

Jacob E. Jencson, Jennifer E. Andrews, Howard E. Bond +39

Nova eruptions, thermonuclear explosions on the surfaces of white dwarfs (WDs), are now recognized to be among the most common shock-powered astrophysical transients. We present th…

AT 2019avd: A novel addition to the diverse population of nuclear transients

A. Malyali, A. Rau, A. Merloni +29

We report on SRG/eROSITA, ZTF, ASAS-SN, Las Cumbres, NEOWISE-R, and Swift XRT/UVOT observations of the unique ongoing event AT 2019avd, located in the nucleus of a previously inact…

A Bright Ultraviolet Excess in the Transitional 02es-like Type Ia Supernova 2019yvq

J. Burke, D. A. Howell, S. K. Sarbadhicary +14

We present photometric and spectroscopic observations of the nearby Type Ia SN 2019yvq, from its discovery 1 day after explosion to 100 days after its peak brightness.…
