The delay time distribution of supernovae from integral-field spectroscopy of nearby galaxies
Asier Castrillo, Yago Ascasibar, Lluís Galbany +6
Constraining the delay-time distribution (DTD) of different supernova (SN) types can shed light on the timescales of galaxy chemical enrichment and feedback processes affecting gal…
Accretion disc cooling and narrow absorption lines in the tidal disruption event AT 2019dsg
G. Cannizzaro, T. Wevers, P. G. Jonker +23
We present the results of a large multi-wavelength follow-up campaign of the Tidal Disruption Event (TDE) \dsg, focusing on low to high resolution optical spectroscopy, X-ray, and…
A Virgo Environmental Survey Tracing Ionised Gas Emission (VESTIGE).IX. The effects of ram pressure stripping down to the scale of individual HII regions in the dwarf galaxy IC 3476
A. Boselli, A. Lupi, B. Epinat +25
We study the IB(s)m galaxy IC 3476 observed in the context of VESTIGE, a blind narrow-band Halpha+[NII] imaging survey of the Virgo cluster. The deep narrow-band (NB) image reveals…
SN 2019muj -- a well-observed Type Iax supernova that bridges the luminosity gap of the class
Barnabás Barna, Tamás Szalai, Saurabh W. Jha +38
We present early-time ( days) observations of SN 2019muj (= ASASSN-19tr), one of the best-observed members of the peculiar SN Iax class. Ultraviolet and optical photometri…
An Amusing Look at the Host of the Periodic Nuclear Transient ASASSN-14ko Reveals a Second AGN
M. A. Tucker, B. J. Shappee, J. T. Hinkle +10
We present Multi-Unit Spectroscopic Explorer (MUSE) integral-field spectroscopy of ESO 253G003, which hosts a known Active Galactic Nucleus (AGN) and the periodic nuclear transi…
Luminous Type II Short-Plateau Supernovae 2006Y, 2006ai, and 2016egz: A Transitional Class from Stripped Massive Red Supergiants
Daichi Hiramatsu, D. Andrew Howell, Takashi J. Moriya +21
The diversity of Type II supernovae (SNe II) is thought to be driven mainly by differences in their progenitor's hydrogen-rich (H-rich) envelope mass, with SNe IIP having long plat…
Optical and Near-Infrared Observations of the Nearby Type Ia Supernova 2017cbv
Lingzhi Wang, Carlos Contreras, Maokai Hu +28
Supernova (SN) 2017cbv in NGC 5643 is one of a handful of type Ia supernovae (SNe~Ia) reported to have excess blue emission at early times. This paper presents extensive $BVRIYJHK_…
Direct evidence of two-component ejecta in supernova 2016gkg from nebular spectroscopy
Hanindyo Kuncarayakti, Gaston Folatelli, Keiichi Maeda +17
Spectral observations of the type-IIb supernova (SN) 2016gkg at 300-800 days are reported. The spectra show nebular characteristics, revealing emission from the progenitor star's m…
SN 2019ehk: A Double-Peaked Ca-rich Transient with Luminous X-ray Emission and Shock-Ionized Spectral Features
Wynn V. Jacobson-Galán, Raffaella Margutti, Charles D. Kilpatrick +64
We present panchromatic observations and modeling of the Calcium-rich supernova 2019ehk in the star-forming galaxy M100 (d16.2 Mpc) starting 10 hours after explosion and c…
The low-luminosity type II SN\,2016aqf: A well-monitored spectral evolution of the Ni/Fe abundance ratio
Tomás E. Müller-Bravo, Claudia P. Gutiérrez, Mark Sullivan +20
Low-luminosity type II supernovae (LL SNe~II) make up the low explosion energy end of core-collapse SNe, but their study and physical understanding remain limited. We present SN\,2…
PS15cey and PS17cke: prospective candidates from the Pan-STARRS Search for Kilonovae
Owen R. McBrien, Stephen J. Smartt, Mark E. Huber +22
Time domain astronomy was revolutionised with the discovery of the first kilonova, AT2017gfo, in August 2017 which was associated with the gravitational wave signal GW170817. Since…
Design and operation of the ATLAS Transient Science Server
