The Roman eXtreme Deep Field (RXDF)
Haojing Yan, Anton M. Koekemoer, Yue Shen +127
The Roman eXtreme Deep Field (RXDF) program is one of the five General Astrophysics Survey (GAS) programs approved for observing time with the Nancy Grace Roman Space Telescope in…
Serendipitous discovery of an almost-dark galaxy in the Virgo Cluster
Minh Ngoc Le, Ignacio Trujillo, Sergio Guerra Arencibia +9
Analogues of extreme Local Group galaxies with very low surface brightnesses and large effective radii must exist elsewhere, still hidden due to current detection limits. We report…
Bridging integrated-light and resolved-star studies of Local Group dwarf spheroidals. A novel use of deep imaging based on amateur telescopes
Sergio Guerra Arencibia, Ignacio Trujillo, Mireia Montes +4
Low-mass galaxies beyond the Local Group can only be studied through their integrated light, yet it remains unclear whether structural parameters inferred from integrated light are…
Ultra-Deep imaging of the starless galaxy candidate Cloud-9
Ignacio Trujillo, Ignacio Ruiz Cejudo, Sergio Guerra Arencibia +1
We report the non-detection of stellar light associated with the dark galaxy candidate Cloud-9. Ultra-deep imaging obtained with HiPERCAM at the Gran Telescopio Canarias (GTC) reac…
How large can galaxies be? Ultra-deep imaging of IC 1101, the most extended known galaxy
Carlos Marrero-de la Rosa, Ignacio Trujillo, Ignacio Ruiz Cejudo +12
The maximum physical extent that galaxies can reach is poorly understood. In this regard, IC 1101, one of the most extended and massive galaxies known, provides a valuable opportun…
Witnessing the rapid growth of disk galaxies over cosmic time using JWST and HST
Samane Raji, Mireia Montes, Ignacio Trujillo +3
Measuring galaxy sizes is fundamental to understanding how galaxies grow and evolve. Traditional methods to measure sizes either trace the concentration of light (i.e., effective r…
