A Linear Relation Between the Color Stretch and the Rising Color Slope of Type Ia Supernovae
Ping Chen, Subo Dong, Chris Ashall +34
Using data from the Complete Nearby () sample of Type Ia Supernovae (CNIa0.02), we discover a linear relation between two parameters derived from the color cur…
On the nature of the X-ray pulsar XTE J1859+083 and its broadband properties
Alexander Salganik, Sergey S. Tsygankov, Anlaug A. Djupvik +5
This work is devoted to the study of the broadband 0.8-79 keV spectral and timing properties of the poorly studied X-ray pulsar XTE J1859+083 during its 2015 outburst based on the…
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…
Carnegie Supernova Project-II: Near-infrared Spectroscopy of Stripped-Envelope Core-Collapse Supernovae
M. Shahbandeh, E. Y. Hsiao, C. Ashall +29
We present 75 near-infrared (NIR; 0.82.5 m) spectra of 34 stripped-envelope core-collapse supernovae (SESNe) obtained by the Carnegie Supernova Project-II (CSP-II), encompass…
Explodability fluctuations of massive stellar cores enable asymmetric compact object mergers such as GW190814
John Antoniadis, David R. Aguilera-Dena, Alejandro Vigna-Gómez +6
The first three observing runs with Advanced LIGO and Virgo have resulted in the detection of binary black hole mergers (BBH) with highly unequal mass components, which are difficu…
Modelling spin evolution of magnetars
Jedrzej A. Jawor, Thomas M. Tauris
The origin and fate of magnetars (young, extremely magnetized neutron stars, NSs) remain unsolved. Probing their evolution is therefore crucial for investigating possible links to…
A Tale of Two Type Ia Supernovae: The fast-declining siblings SNe 2015bo and 1997cn
W. B. Hoogendam, C. Ashall, L. Galbany +18
We present optical and near-infrared photometric and spectroscopic observations of the fast-declining Type Ia Supernova (SN) 2015bo. SN 2015bo is under-luminous (M = -17.67 $\p…
Intermediate-luminosity red transients: Spectrophotometric properties and connection to electron-capture supernova explosions
Y. -Z. Cai, A. Pastorello, M. Fraser +56
We present the spectroscopic and photometric study of five intermediate-luminosity red transients (ILRTs), namely AT 2010dn, AT 2012jc, AT 2013la, AT 2013lb, and AT 2018aes. They s…
ASAS-SN search for optical counterparts of gravitational-wave events from the third observing run of Advanced LIGO/Virgo
T. de Jaeger, B. J. Shappee, C. S. Kochanek +6
We report on the search for electromagnetic counterparts to the nine gravitational-wave events with a 60\% probability of containing a neutron star during the third (O3) LIGO-Vi…
SN 2018agk: A Prototypical Type Ia Supernova with a Smooth Power-law Rise in Kepler (K2)
Qinan Wang, Armin Rest, Yossef Zenati +73
We present the 30-min cadence Kepler/K2 light curve of the Type Ia supernova (SN Ia) SN 2018agk, covering approximately one week before explosion, the full rise phase and the decli…
A puzzle solved after two decades: SN 2002gh among the brightest of superluminous supernovae
Régis Cartier, Mario Hamuy, Carlos Contreras +9
We present optical photometry and spectroscopy of the superluminous SN 2002gh from maximum light to days, obtained as part of the Carnegie Type II Supernova (CATS) project.…
SRG/ART-XC discovery of SRGA J204318.2+443815: towards the complete population of faint X-ray pulsars
A. A. Lutovinov, S. S. Tsygankov, I. A. Mereminskiy +19
We report a discovery of a new long-period X-ray pulsar SRGA J204318.2+443815/SRGe J204319.0+443820 in the Be binary system. The source was found in the second all-sky survey by th…
