LoVoCCS. III. Third Generation Pipeline & The Hercules Supercluster
Anthony M. Englert, Shenming Fu, Ian Dell'Antonio +29
The Local Volume Complete Cluster Survey (LoVoCCS) is a volume-complete survey of over one-hundred nearby (), X-ray luminous ($L_{500} > 10^{44} \text{ erg s}^{-1}…
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…
Deep imaging of the very isolated dwarf galaxy NGC6789
Ignacio Trujillo, Sergio Guerra Arencibia, Ignacio Ruiz Cejudo +3
We present deep optical imaging of the extremely isolated dwarf galaxy NGC 6789, obtained with the new 2-meter Two-meter Twin Telescope (TTT3) at Teide Observatory. Despite its loc…
The Intracluster Light of Abell 3667: Unveiling an Optical Bridge in LSST Precursor Data
Anthony Englert, Ian Dell'Antonio, Mireia Montes
Intracluster light, the diffuse glow of stars stripped from galaxies during a cluster's formation, is an established tracer of a cluster's dynamical history. The upcoming Vera C. R…
Constraining the shape of dark matter haloes using only starlight. I. A new technique and its application to the galaxy Nube
Jorge Sanchez Almeida, Ignacio Trujillo, Mireia Montes +1
We present a new technique to constrain the gravitational potential of a galaxy from the observed stellar mass surface density alone under a number of assumptions. It uses the clas…
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 th…
LIGHTS. Survey Overview and a Search for Low Surface Brightness Satellite Galaxies
Dennis Zaritsky, Giulia Golini, Richard Donnerstein +12
We present an overview of the LIGHTS (LBT Imaging of Galactic Halos and Tidal Structures) survey, which currently includes 25 nearby galaxies that are on average 1 mag faint…
Deep HST imaging favors the bulgeless edge-on galaxy explanation for the hypothetical stellar wake created by a runaway supermassive black hole
Mireia Montes, Jorge Sánchez Almeida, Ignacio Trujillo
A long linear structure recently discovered could be the stellar wake produced by the passage of a runaway supermassive black hole (SMBH) or, alternatively, a bulgeless edge-on gal…
Exploring the nature of dark matter with the extreme galaxy AGC 114905
Pavel E. Mancera Piña, Giulia Golini, Ignacio Trujillo +1
AGC 114905 is a dwarf gas-rich ultra-diffuse galaxy seemingly in tension with the cold dark matter (CDM) model. Specifically, the galaxy appears to have an extremely low-density ha…
LoVoCCS. II. Weak Lensing Mass Distributions, Red-Sequence Galaxy Distributions, and Their Alignment with the Brightest Cluster Galaxy in 58 Nearby X-ray-Luminous Galaxy Clusters
Shenming Fu, Ian Dell'Antonio, Zacharias Escalante +31
The Local Volume Complete Cluster Survey (LoVoCCS) is an on-going program to observe nearly a hundred low-redshift X-ray-luminous galaxy clusters (redshifts and X-ray…
Ultra-deep imaging of NGC1052-DF2 and NGC1052-DF4 to unravel their origins
Giulia Golini, Mireia Montes, Eleazar R. Carrasco +2
A number of scenarios have been proposed to explain the low velocity dispersion (and hence possible absence of dark matter) of the low surface brightness galaxies NGC1052-DF2 and N…
An almost dark galaxy with the mass of the Small Magellanic Cloud
Mireia Montes, Ignacio Trujillo, Ananthan Karunakaran +9
Almost Dark Galaxies are objects that have eluded detection by traditional surveys such as the Sloan Digital Sky Survey (SDSS). The low surface brightness of these galaxies ((…
Optimizing Roman's High Latitude Wide Area Survey for Low Surface Brightness Astronomy
Mireia Montes, Francesca Annibali, Michele Bellazzini +20
One of the last remaining frontiers in optical/near-infrared observational astronomy is the low surface brightness regime (LSB, V-band surface brightness, 27 AB mag/arcsec$^…
The cosmic assembly of stellar haloes in massive Early-Type Galaxies
F. Buitrago, I. Trujillo, E. Curtis-Lake +5
Using the exquisite depth of the Hubble Ultra Deep Field (HUDF12 programme) dataset, we explore the ongoing assembly of the outermost regions of the most massive galaxies ($\rm M_{…
The innermost globular clusters of M87
M. Montes, J. A. Acosta-Pulido, M. A. Prieto +1
We present a comprehensive multiwavelength photometric analysis of the innermost (3x3 square kpc) 110 globular clusters (GCs) of M87. Their spectral energy distributions (SEDs) wer…
Age and metallicity gradients support hierarchical formation for M87
Mireia Montes, Ignacio Trujillo, M. Almudena Prieto +1
In order to probe the inside-out formation of the most massive galaxies in the Universe, we have explored the radial (0.1 < R < 8 kpc) variation of the spectral energy distribution…
The SED of Low-Luminosity AGNs at high-spatial resolution
J. A. Fernández-Ontiveros, M. A. Prieto, J. A. Acosta-Pulido +1
The inner structure of AGNs is expected to change below a certain luminosity limit. The big blue bump, footprint of the accretion disk, is absent for the majority of low-luminosity…
The most recent burst of Star Formation in the Massive Elliptical Galaxy NGC 1052
J. A. Fernández-Ontiveros, C. López-Sanjuan, M. Montes +2
High-spatial resolution near-infrared (NIR) images of the central 24 x 24 arcsec^2 (~ 2 x 2 kpc^2) of the elliptical galaxy NGC 1052 reveal a total of 25 compact sources randomly d…
