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…
Concerning Colour: The Effect of Environment on Type Ia Supernova Colour in the Dark Energy Survey
L. Kelsey, M. Sullivan, P. Wiseman +67
Recent analyses have found intriguing correlations between the colour () of type Ia supernovae (SNe Ia) and the size of their 'mass-step', the relationship between SN Ia host ga…
A Convolutional Neural Network Approach to Supernova Time-Series Classification
Helen Qu, Masao Sako, Anais Moller +1
One of the brightest objects in the universe, supernovae (SNe) are powerful explosions marking the end of a star's lifetime. Supernova (SN) type is defined by spectroscopic emissio…
A galaxy-driven model of type Ia supernova luminosity variations
P. Wiseman, M. Vincenzi, M. Sullivan +59
Type Ia supernovae (SNe Ia) are used as standardisable candles to measure cosmological distances, but differences remain in their corrected luminosities which display a magnitude s…
Core-collapse Supernovae in the Dark Energy Survey: Luminosity Functions and Host Galaxy Demographics
M. Grayling, C. P. Gutiérrez, M. Sullivan +73
We present the luminosity functions and host galaxy properties of the Dark Energy Survey (DES) core-collapse supernova (CCSN) sample, consisting of 69 Type II and 50 Type Ibc spect…
Type Ia supernova Hubble diagrams with host galaxy photometric redshifts
V. Ruhlmann-Kleider, C. Lidman, A. Möller
The case of SN Ia Hubble diagrams from photometrically selected samples using photometric SN host galaxy redshifts is investigated. The host redshift uncertainties and the contamin…
