TDCOSMO XVII. New time delays in 22 lensed quasars from optical monitoring with the ESO-VST 2.6m and MPG 2.2m telescopes
Frédéric Dux, Martin Millon, Aymeric Galan +29
We present new time delays, the main ingredient of time delay cosmography, for 22 lensed quasars resulting from high-cadence r-band monitoring on the 2.6 m ESO VLT Survey Telescope…
VELOcities of CEpheids (VELOCE) I. High-precision radial velocities of Cepheids
Richard I. Anderson, Giordano Viviani, Shreeya S. Shetye +27
This first VELOCE data release comprises 18,225 high-precision RV measurements of 258 bona fide classical Cepheids on both hemispheres collected mainly between 2010 and 2022, along…
The Magnificent Five Images of Supernova Refsdal: Time Delay and Magnification Measurements
Patrick L. Kelly, Steven Rodney, Tommaso Treu +28
In late 2014, four images of Supernova (SN) "Refsdal," the first known example of a strongly lensed SN with multiple resolved images, were detected in the MACS J1149 galaxy-cluster…
Constraints on the Hubble constant from Supernova Refsdal's reappearance
Patrick L. Kelly, Steven Rodney, Tommaso Treu +27
The gravitationally lensed Supernova Refsdal appeared in multiple images, produced through gravitational lensing by a massive foreground galaxy cluster. After the supernova appeare…
Hot Exoplanet Atmospheres Resolved with Transit Spectroscopy (HEARTS) VIII. Nondetection of sodium in the atmosphere of the aligned planet KELT-10b
M. Steiner, O. Attia, D. Ehrenreich +17
We searched for potential atmospheric species in KELT-10b, focusing on sodium doublet lines (Na i; 589 nm) and the Balmer alpha line (H ; 656 nm) in the transmission spectrum. F…
Radial Autoencoders for Enhanced Anomaly Detection
Mihai-Cezar Augustin, Vivien Bonvin, Regis Houssou +2
In classification problems, supervised machine-learning methods outperform traditional algorithms, thanks to the ability of neural networks to learn complex patterns. However, in t…
