Streamlined Lensed Quasar Identification in Multiband Images via Ensemble Networks
Irham Taufik Andika, Sherry H. Suyu, Raoul Cañameras +6
Quasars experiencing strong lensing offer unique viewpoints on subjects related to the cosmic expansion rate, the dark matter profile within the foreground deflectors, and the quas…
The puzzling properties of the MACS1149-JD1 galaxy at z=9.11
Massimo Stiavelli, Takahiro Morishita, Marco Chiaberge +6
We analyze new JWST NIRCam and NIRSpec data on the redshift 9.11 galaxy MACS1149-JD1. Our NIRCam imaging data reveal that JD1 comprises three spatially distinct components. Our spe…
The impact of human expert visual inspection on the discovery of strong gravitational lenses
Karina Rojas, Thomas E. Collett, Daniel Ballard +53
We investigate the ability of human 'expert' classifiers to identify strong gravitational lens candidates in Dark Energy Survey like imaging. We recruited a total of 55 people that…
Observations of the Very Young Type Ia Supernova 2019np with Early-excess Emission
Hanna Sai, Xiaofeng Wang, Nancy Elias-Rosa +30
Early-time radiative signals from type Ia supernovae (SNe Ia) can provide important constraints on the explosion mechanism and the progenitor system. We present observations and an…
