Discovery of a gravitational arc candidate at photometric redshift 1.4 in MACS J0308.9+2645 from a catalogue-based search of JWST imaging
Homer Dávila Gutiérrez
We report a previously uncatalogued gravitational arc candidate (A1) in the massive RELICS cluster MACS J0308.9+2645 (z_l = 0.356), identified in public JWST/NIRCam imaging from pr…

Testing the recovery of the NGC 6505 Einstein ring in deep OSN 1.5-m imaging
Homer Dávila Gutiérrez, Julio Carlos Bertua Marasca, Alejandro Heredia Teva +4
The discovery of a complete Einstein ring around the nearby elliptical galaxy NGC 6505 (z = 0.042) by the Euclid mission provides a rare, precisely characterised low-redshift stron…
