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 ((…
The truncation of the disk of NGC 4565: Detected up to z=4 kpc, with star formation, and affected by the warp
Cristina Martinez-Lombilla, Raul Infante-Sainz, Felipe Jimenez-Ibarra +5
Context: The hierarchical model of galaxy formation suggests that galaxies are continuously growing. However, our position inside the Milky Way prevents us from studying the disk e…
A giant thin stellar stream in the Coma Galaxy Cluster
Javier Román, R. Michael Rich, Niusha Ahvazi +7
The study of dynamically cold stellar streams reveals information about the gravitational potential where they reside and provides important constraints on dark matter properties.…
Prospects for future studies using deep imaging: Analysis of individual Galactic cirrus filaments
Anton A. Smirnov, Sergey S. Savchenko, Denis M. Poliakov +6
The presence of Galactic cirrus is an obstacle for studying both faint objects in our Galaxy and low surface brightness extragalactic structures. With the aim of studying individua…
A giant umbrella-like stellar stream around the tidal ring galaxy NGC 922
David Martinez-Delgado, Santi Roca-Fabrega, Juan Miro-Carretero +6
Tidal ring galaxies are observed rarely in the local universe due to their intrinsically transient nature. The tidal ring structures are the result of strong interactions between g…
Fractal dimension of optical cirrus in Stripe82
Alexander A. Marchuk, Anton A. Smirnov, Aleksandr V. Mosenkov +4
The geometric characteristics of dust clouds provide important information on the physical processes that structure such clouds. One of such characteristics is the fractal dim…
Introducing the LBT Imaging of Galactic Halos and Tidal Structures (LIGHTS) survey. A preview of the low surface brightness Universe to be unveiled by LSST
Ignacio Trujillo, Mauro D'Onofrio, Dennis Zaritsky +10
We present the first results of the LBT Imaging of Galaxy Haloes and Tidal Structures (LIGHTS) survey. LIGHTS is an ongoing observational campaign with the 2x8.4m Large Binocular T…
Tracing satellite planes in the Sculptor group: I. Discovery of three faint dwarf galaxies around NGC 253
David Martinez-Delgado, Dmitry Makarov, Behnam Javanmardi +7
In the last years, a new generation of large-scale imaging surveys have probed wide field regions around some nearby galaxies at unprecedented low surface brightness regime (~28.0-…
A feather on the hat: Tracing the giant stellar stream around the Sombrero galaxy
David Martinez-Delgado, Javier Roman, Denis Erkal +7
Recent evidence of extremely metal-rich stars found in the Sombrero galaxy (M104) halo suggests that this galaxy has undergone a recent major merger with a relatively massive galax…
Hidden depths in the local Universe: The Stellar Stream Legacy Survey
David Martinez-Delgado, Andrew P. Cooper, Javier Roman +26
Mergers and tidal interactions between massive galaxies and their dwarf satellites are a fundamental prediction of the Lambda-Cold Dark Matter cosmology. These events are thought t…
The galaxy "missing dark matter" NGC1052-DF4 is undergoing tidal disruption
Mireia Montes, Raúl Infante-Sainz, Alberto Madrigal-Aguado +4
The existence of long-lived galaxies lacking dark matter represents a challenge to our understanding of how galaxies form. Here, we present evidence that explains the lack of dark…
Convergence of Lobatto-type Runge-Kutta methods for partitioned differential-algebraic systems of index 2
Rodrigo Takuro Sato Martín de Almagro
In this paper we propose a numerical scheme for partitioned systems of index 2 DAEs, such as those arising from nonholonomic mechanical problems and prove the order of a certain cl…
A distance of 13 Mpc resolves the claimed anomalies of the galaxy lacking dark matter
Ignacio Trujillo, Michael A. Beasley, Alejandro Borlaff +10
The claimed detection of a diffuse galaxy lacking dark matter represents a possible challenge to our understanding of the properties of these galaxies and galaxy formation in gener…
Spectroscopic characterisation of the stellar content of ultra diffuse galaxies
T. Ruiz-Lara, M. A. Beasley, J. Falcón-Barroso +7
Understanding the peculiar properties of Ultra Diffuse Galaxies (UDGs) via spectroscopic analysis is a challenging task requiring very deep observations and exquisite data reductio…
