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 +18
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…
JWST spectra are consistent with the edge-on star-forming galaxy scenario for the "runaway supermassive black hole"
Jorge Sanchez Almeida, Ignacio Trujillo, Sebastian F. Sanchez +1
The linear structure reported by van Dokkum et al. (2023) has been proposed as either a massive stellar wake produced by a runaway supermassive black hole (SMBH) or a bulgeless edg…
A targeted, parallax-based search for Planet Nine
Hector Socas-Navarro, Ignacio Trujillo
The hypothesized Planet Nine is thought to reside in the distant outer solar system, potentially explaining various anomalies in the orbits of extreme trans-Neptunian objects (ETNO…
LIGHTS. A robust technique to identify galaxy edges
Giulia Golini, Ignacio Trujillo, Dennis Zaritsky +19
The LIGHTS survey is imaging galaxies at a depth and spatial resolution comparable to what the Legacy Survey of Space and Time (LSST) will produce in 10 years (i.e., 31 mag/a…
LIGHTS. The extended point spread functions of the LIGHTS survey at the LBT
Nafise Sedighi, Zahra Sharbaf, Ignacio Trujillo +13
With the arrival of the next generation of ultra-deep optical imaging surveys reaching 30 mag/arcsec (3; 10"10"), the removal of scattered light due to…
