PublicationA galaxy-driven model of type Ia supernova luminosity variations
Type Ia supernovae (SNe Ia) are used as standardizable candles to measure cosmological distances, but differences remain in their corrected luminosities which...
PublicationA Gemini snapshot survey for double degenerates
We present the results from a Gemini snapshot radial-velocity survey of 44 low-mass white-dwarf candidates selected from the Sloan Digital Sky Survey (SDSS)...
PublicationA luminous stellar outburst during a long-lasting eruptive phase first, and then SN IIn 2018cnf
We present the results of the monitoring campaign of the Type IIn supernova (SN) 2018cnf (a.k.a. ASASSN-18mr). It was discovered about ten days before the...

PublicationA study of the Type II-P supernova 2003gd in M74
We present photometric and spectroscopic data of the Type II-P supernova (SN II-P) 2003gd, which was discovered in M74 close to the end of its plateau phase. SN...
