astro-ph.GA2026

Surveying the Universe in 4D: Beating Cosmic Variance with Wide-Field Slitless Spectroscopy from HST, JWST, Euclid, Roman, and Beyond

Andreea Petric, Gaël Noirot, Stacey Alberts +71

We summarize strategies, lessons learned, and future directions from the Space Telescope Science Institute workshop Surveying the Universe in 4D: Beating Cosmic Variance with Wide-…

astro-ph.HE2026

A multiwavelength view of the nearby Calcium-Strong Transient SN 2025coe in the X-Ray, Near-Infrared, and Radio Wavebands

Sahana Kumar, Raphael Baer-Way, Aravind P. Ravi +18

Calcium-strong transients (CaSTs) are a subclass of faint and rapidly evolving supernovae (SNe) that exhibit strong calcium features and notably weak oxygen features. The small but…

The Double-Peaked Calcium-Strong SN 2025coe: Progenitor Constraints from Early Interaction and Ejecta Asymmetries

Aravind P. Ravi, Sahana Kumar, Raphael Baer-Way +47

Supernova (SN) 2025coe at a distance of ∼25 Mpc is the second-closest calcium-strong (CaST) transient. It was discovered at a large projected offset of ∼34 kpc from its p…
