Relative frequencies of core-collapse supernovae as a function of metallicity: observations vs theoretical predictions
Claudia P. Gutiérrez, LluÃs Galbany, Joseph P. Anderson +4
Understanding supernova (SN) progenitors remains a major challenge in astrophysics, as it involves untangling the complex interplay between stellar physics (e.g., evolution, binari…
Narrow absorption lines from intervening material in supernovae. II. Galaxy properties
Santiago González-Gaitán, Claudia P. Gutiérrez, Gonçalo Martins +11
The interstellar medium (ISM) has a number of tracers such as the Na I D 5890, 5896 AA absorption lines that are evident in the spectra of galaxies but also in those of individual…
Fishing for the Optimal Roman High Latitude Time Domain Survey: Cosmological Constraints for 1,000 Possible Surveys
David Rubin, Greg Aldering, Andy Fruchter +9
The upcoming Nancy Grace Roman Space Telescope is set to conduct a generation-defining SN Ia cosmology measurement with its High Latitude Time Domain Survey (HLTDS). However, betwe…
A Reassessment of the Pantheon+ and DES 5YR Calibration Uncertainties: Dovekie
B. Popovic, W. D. Kenworthy, M. Ginolin +21
Type Ia Supernovae (SNe Ia) are crucial tools to measure the accelerating expansion of the universe, comprising thousands of SNe across multiple telescopes. Accurate measurements o…
ZTF SN Ia DR2: The diversity and relative rates of the thermonuclear SN population
G. Dimitriadis, U. Burgaz, M. Deckers +28
The Zwicky Transient Facility SN Ia Data Release 2 (ZTF SN Ia DR2) contains more than 3,000 Type Ia supernovae (SNe Ia), providing the largest homogeneous low-redshift sample of SN…
