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…
From M100 to NGC 7331: A Multiband Study and Physical Parameters in Nearby Galaxies
Julio C. Bertua Marasca, Homer Dávila Gutiérrez, Víctor Huamán Ticona +2
We study five nearby galaxies (M100/NGC 4321, NGC 1300, M 74, M 60, and NGC 7331) by combining multiband imaging (optical, UV, NIR, and X-rays) with simple photometric measurements…
