Extreme Stellar Death and Galaxy Feedback at z = 2: A Rest-frame Ultraviolet Characterization of the Strongly Lensed Superluminous Supernova 2025wny
Willem B. Hoogendam, David O. Jones, Christopher J. Storfer +26
We present photometric and spectroscopic follow-up observations of the strongly-lensed H-poor superluminous supernova (SLSN) 2025wny at . We use integral-field Keck-II/…
Nearby Supernova Science in the Era of High Cadence, Deep Time Domain Surveys
David J. Sand, Bhagya Subrayan, Conor L. Ransome +41
We discuss science opportunities for nearby supernovae (SNe) in the era of the Vera C. Rubin Observatory's Legacy Survey of Space and Time (LSST), emphasizing the youngest phases o…
DETECT: Real-Time Identification of Transients with DESI Spectroscopic Redshift
Yu-Hsing Lee, Ting-Wan Chen, Ze-Ning Wang +10
Wide-field surveys now report thousands of transients per month, while spectra are obtained for only a few per cent of them. We present DETECT (DESI--Transient Event Cross-matching…
Aarmed with Data: Bumps, Outflows, and Disk-like Emission in TDE 2025aarm
Aysha Aamer, Kate D. Alexander, Charlotte R. Angus +43
The origin of the optical emission in tidal disruption events (TDEs) remains one of the major outstanding questions in the field, in part due to the limited number of nearby events…
A Two-month, Galaxy-targeted NIR Follow-up of the Sub-solar-mass Gravitational Wave Candidate S251112cm: Probing Electromagnetic Counterpart Scenarios
Gregory S. H. Paek, Felipe Olivares E., Willem B. Hoogendam
S251112cm is a nearby (~Mpc) compact-binary merger candidate with a high inferred probability that at least one component is below . This event provides a ra…
Characterizing the disruption of Böotes III: a missing link in the Galactic halo?
Jaclyn Jensen, Daniel A. Boyea, Alan W. McConnachie +14
The Böotes III (Boo3) dwarf galaxy has long been suspected of being the progenitor of Styx, a ~50°-long stellar stream that was simultaneously discovered in the same region of sky.…
7DT Insight: Variability in Young Stellar Objects
Mi-Ryang Kim, Jeong-Eun Lee, Myungshin Im +11
Photometric variability in young stellar objects (YSOs) provides critical insight into the mechanisms of mass accretion, disk evolution, and circumstellar extinction in early stell…
KMTNet Synoptic Survey of Southern Sky III: The First Data Release
Seo-Won Chang, Myungshin Im, Mankeun Jeong +13
We present the first public data release (DR1) of the KMTNet Synoptic Survey of Southern Sky (KS4). This deep, wide-field imaging survey covers a southern footprint of -85$^{\circ}…
KMTNet Synoptic Survey of Southern Sky II: Data Reduction and Real-Time Transient Detection Pipeline
Mankeun Jeong, Myungshin Im, Joonho Kim +9
We present a comprehensive pipeline developed for the image processing of the KMTNet Synoptic Survey of the Southern Sky (KS4) Data Release 1. This pipeline encompasses several key…
Pre-perihelion Emergence of the CN Gas Coma in 3I/ATLAS Temporally and Spatially Resolved by the 7-Dimensional Telescope
Gregory S. H. Paek, Myungshin Im, Mankeun Jeong +8
We present time-series medium-band (R~20-40) observations of the third interstellar object 3I/ATLAS (C/2025 N1) obtained with the 7-Dimensional Telescope (7DT), enabling spatially…
