A Luminous Red Optical Flare and Hard X-ray Emission in the Tidal Disruption Event AT2024kmq
Anna Y. Q. Ho, Yuhan Yao, Tatsuya Matsumoto +30
We present the optical discovery and multiwavelength follow-up observations of AT2024kmq, a likely tidal disruption event (TDE) associated with a supermassive ($M_{\rm BH}\sim 10^{…
Euclid: A complete Einstein ring in NGC 6505
C. M. O'Riordan, L. J. Oldham, A. Nersesian +195
We report the discovery of a complete Einstein ring around the elliptical galaxy NGC 6505, at . This is the first strong gravitational lens discovered in Euclid and the fi…
The SPHEREx Target List of Ice Sources (SPLICES)
Matthew L. N. Ashby, Joseph L. Hora, Kiran Lakshmipathaiah +16
One of the primary objectives of the SPHEREx mission is to understand the origin of molecules such as H2O, CO2, and other volatile compounds at the early stages of planetary system…
Euclid preparation LX. The use of HST images as input for weak-lensing image simulations
Euclid Collaboration, D. Scognamiglio, T. Schrabback +245
Data from the Euclid space telescope will enable cosmic shear measurements with very small statistical errors, requiring corresponding systematic error control level. A common appr…
Clumps as multiscale structures in cosmic noon galaxies
Boris S Kalita, Tomoko L Suzuki, Daichi Kashino +31
Star-forming clumps have been found to significantly influence the star formation of gas-rich galaxies. Using public data from JWST/NIRCam (COSMOS-Web) and ALMA (FMOS-COSMOS)…
