No evidence for dynamical dark energy from the Combo correlation of GRBs
Marco Muccino, Massimo Della Valle, Luca Izzo +1
Recently, the Dark Energy Spectroscopic Instrument (DESI) collaboration has presented results indicating that dark energy may exhibit dynamical behavior. Calibrated gamma-ray burst…
Normal or transitional? The evolution and properties of two type Ia supernovae in the Virgo cluster
L. Izzo, C. Gall, N. Khetan +47
Type Ia supernovae (SNe Ia) are among the most precise cosmological distance indicators used to study the expansion history of the Universe. The vast increase of SN Ia data due to…
An optical--mid-infrared color evolution tool for nova identification using WISE data
Joseph Onuegbu, Dafne Guetta, Yael Hillman +2
We present a novel approach for characterizing nova candidates by exploiting the infrared capabilities of the Wide-field Infrared Survey Explorer (WISE) catalog. We developed a pip…
Unveiling the central engine of core-collapse supernovae in the Local Universe: NS or BH?
Maurice H. P. M. van Putten, Maryam A. Abchouyeh, Massimo Della Valle
The physical trigger powering supernovae following the core collapse of massive stars is believed to involve a neutron star (NS) or a black hole (BH), depending largely on progenit…
