JWST Nebular Spectroscopy of SN 2023qov: Circumstellar Dust Emission in a Normal Type Ia Supernova
Abstract We present panchromatic observations of the Type Ia supernova (SN Ia) 2023qov, ranging from ∼2 weeks before to ∼1 yr after maximum light. JWST near- and mid-infrared spectra at +276 and +363 days show ∼400 K dust emission that cools by ∼75 K between epochs, the first una...

Post-perihelion Photometric and Spectroscopic Monitoring of the Interstellar Comet 3I/ATLAS
Abstract The third interstellar object, comet 3I/ATLAS, was observed using various Indian telescopes during its post-perihelion evolution. We carried out imaging and spectroscopic observations of the comet at multiple epochs using the 0.5–m, 1.2–m, and 2.5–m telescopes of the Phy...

Abstract We present a multiwavelength study of the long-duration gamma-ray burst GRB 230328B, combining prompt γ-ray observations with exceptionally early simultaneous optical photometry and extensive X-ray, radio, and host-galaxy follow-up. NUTTELA-TAO began simultaneous g′r′i′...
