slicersim: A python package to simulate image slicer spectroscopic observations -- application to the Lazuli Spectrograph
M. Rigault, Y. Copin, G. Aldering +8
Integral Field Spectroscopy (IFS) is a key technique to study galaxies, stellar and planetary systems, and transients, by spatially splitting the scene and dispersing this light on…
Banana Split: Improved Cosmological Constraints with Two Light-Curve-Shape and Color Populations Using Union3.1+UNITY1.8
David Rubin, Taylor Hoyt, Greg Aldering +1
SNe Ia have been used to provide key constraints on the equation-of-state parameter of dark energy. They are generally standardized under the assumption that they belong to a singl…
Union3.1: Self-consistent Measurements of Host Galaxy Properties for 2000 Type Ia Supernovae
Taylor J. Hoyt, David Rubin, Greg Aldering +3
The determination of distances using time-series photometry of Type Ia supernovae (SNe Ia) relies on a ~5% empirical correction related to the properties of their host galaxies, e.…
Three-dimensional scene reconstruction using Roman slitless spectra
Tri L. Astraatmadja, Andrew S. Fruchter, Susana E. Deustua +10
The Nancy Grace Roman Space Telescope will carry out a wide-field imaging and slitless spectroscopic survey of Type Ia Supernovae to improve our understanding of dark energy. Cruci…
The Lazuli Space Observatory: Architecture & Capabilities
Arpita Roy, Stuart Feldman, Pete Klupar +51
The Lazuli Space Observatory is a 3-meter aperture astronomical facility designed for rapid-response observations and precision astrophysics across visible to near-infrared wavelen…
ZTF-SEDm Type Ia supernova sample for Twins Embedding spectrophotometric standardisation
C. Ganot, Y. Copin, M. Rigault +26
This paper has two aims: the first one is to build a large homogeneous spectrophotometric Type Ia supernova (SN Ia) sample, using 3069 spectra from the second Zwicky Transient Faci…
