The prevalence and influence of circumstellar material around hydrogen-rich supernova progenitors
Rachel J. Bruch, Avishay Gal-Yam, Ofer Yaron +44
Narrow transient emission lines (flash-ionization features) in early supernova (SN) spectra trace the presence of circumstellar material (CSM) around the massive progenitor stars o…
SN 2021fxy: Mid-Ultraviolet Flux Suppression is a Common Feature of Type Ia Supernovae
J. M. DerKacy, S. Paugh, E. Baron +26
We present ultraviolet (UV) to near-infrared (NIR) observations and analysis of the nearby Type Ia supernova SN 2021fxy. Our observations include UV photometry from Swift/UVOT, UV…
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…
Photometric and spectroscopic analysis of the Type II SN 2020jfo with a short plateau
B. Ailawadhi, R. Dastidar, K. Misra +34
We present high-cadence photometric and spectroscopic observations of SN~2020jfo in ultraviolet and optical/near-infrared bands starting from to days after the…
Carnegie Supernova Project-II: Near-infrared spectral diversity and template of Type Ia Supernovae
Jing Lu, Eric Y. Hsiao, Mark M. Phillips +30
We present the largest and most homogeneous collection of near-infrared (NIR) spectra of Type Ia supernovae (SNe Ia): 339 spectra of 98 individual SNe obtained as part of the Carne…
A JWST Near- and Mid-Infrared Nebular Spectrum of the Type Ia Supernova 2021aefx
Lindsey A. Kwok, Saurabh W. Jha, Tea Temim +55
We present JWST near- and mid-infrared spectroscopic observations of the nearby normal Type Ia supernova SN 2021aefx in the nebular phase at days past maximum light. Our Nea…
Reveals Spectacular Light Echoes Associated with the Stripped-envelope Supernova 2016adj in the Iconic Dust Lane of Centaurus A
Maximilian Stritzinger, Francesco Taddia, Stephen S. Lawrence +6
We present a multi-band sequence of images documenting the emergence and evolution of multiple light echoes (LEs) linked to the stripped-envelope supernova…
A population of Type Ibc supernovae with massive progenitors; broad lightcurves not uncommon in (i)PTF
E. Karamehmetoglu, J. Sollerman, F. Taddia +9
If high-mass stars (>20-25 Msun) are the progenitors of stripped-envelope (SE) supernovae (SNe), their massive ejecta should lead to broad, long-duration lightcurves (LCs). Instead…
Near-infrared and Optical Nebular-phase Spectra of Type Ia Supernovae SN 2013aa and SN 2017cbv in NGC 5643
Sahana Kumar, Eric Y. Hsiao, Chris Ashall +23
We present multi-wavelength time-series spectroscopy of SN 2013aa and SN 2017cbv, two Type Ia supernovae (SNe Ia) on the outskirts of the same host galaxy, NGC 5643. This work util…
The ASAS-SN Bright Supernova Catalog -- V. 2018-2020
K. D. Neumann, T. W. -S. Holoien, C. S. Kochanek +55
We catalog the 443 bright supernovae discovered by the All-Sky Automated Survey for Supernovae (ASAS-SN) in along with the 519 supernovae recovered by ASAS-SN and 516 a…
The Absolute Magnitudes of 1991T-like Supernovae
M. M. Phillips, C. Ashall, Christopher R. Burns +20
1991T-like supernovae are the luminous, slow-declining extreme of the Branch shallow-silicon (SS) subclass of Type Ia supernovae. They are distinguished by extremely weak Ca II H &…
Observations of the Very Young Type Ia Supernova 2019np with Early-excess Emission
Hanna Sai, Xiaofeng Wang, Nancy Elias-Rosa +30
Early-time radiative signals from type Ia supernovae (SNe Ia) can provide important constraints on the explosion mechanism and the progenitor system. We present observations and an…
Discovery of a pulse-phase-transient cyclotron line in the X-ray pulsar Swift J1808.4-1754 and identification of an optical companion
Alexander Salganik, Sergey S. Tsygankov, Alexander A. Lutovinov +3
In this work, the temporal and spectral properties of the poorly studied X-ray pulsar Swift J1808.41754 were investigated in the 0.8-79 keV energy range based on the data from t…
A Speed Bump: SN 2021aefx Shows that Doppler Shift Alone can Explain Early-Excess Blue Flux in Some Type Ia Supernovae
C. Ashall, J. Lu, B. J. Shappee +17
We present early-time photometric and spectroscopic observations of the Type Ia Supernova (SN Ia) 2021aefx. The early time u-band light curve shows an excess flux when compared to…
