Carnegie Supernova Project II: The Slowest Rising Type Ia Supernova LSQ14fmg and Clues to the Origin of Super-Chandrasekhar/03fg-like Events
(IOP Publishing, 2020)
The Type Ia supernova (SN Ia) LSQ14fmg exhibits exaggerated properties that may help to reveal the origin of the "super-Chandrasekhar" (or 03fg-like) group. The optical spectrum is typical of a 03fg-like SN Ia, but the ...
The Emergence of the Infrared Transient VVV-WIT-06
(Institute of Physics Publishing, 2017-11)
We report the discovery of an enigmatic large-amplitude (ΔKs >10.5 mag) transient event in near-IR data obtained by the VISTA Variables in the Via Lactea (VVV) ESO Public Survey. The object (designated VVV-WIT- 06) is ...
INTERACTING SUPERNOVAE AND SUPERNOVA IMPOSTORS: SN 2009ip, IS THIS THE END?
(The American Astronomical Society, 2013-04)
We report the results of a three-year-long dedicated monitoring campaign of a restless luminous blue variable (LBV)
in NGC 7259. The object, named SN 2009ip, was observed photometrically and spectroscopically in the optical ...
The Emergence of the Infrared Transient VVV-WIT-06
(Institute of Physics, 2017)
We report the discovery of an enigmatic large-amplitude (DKs > 10.5 mag) transient event in near-IR data
obtained by the VISTA Variables in the Via Lactea (VVV) ESO Public Survey. The object (designated VVV-WIT-
06) is ...
BONA FIDE, STRONG-VARIABLE GALACTIC LUMINOUS BLUE VARIABLE STARS ARE FAST ROTATORS: DETECTION OF A HIGH ROTATIONAL VELOCITY IN HR CARINAE
(IOP PUBLISHING LTD, 2009)
We report optical observations of the luminous blue variable (LBV) HR Carinae which show that the star has reached a visual minimum phase in 2009. More importantly, we detected absorptions due to Si lambda lambda 4088-4116. ...
Detection of a Type IIn Supernova in Optical Follow-up Observations of IceCube Neutrino Events
(IOP Publishing, 2015-09-18)
The IceCube neutrino observatory pursues a follow-up program selecting interesting neutrino events in real-time and issuing alerts for electromagnetic follow-up observations. In 2012 March, the most significant neutrino ...
