J-ATLAS: Javalambre Andromeda and Triangulum Legacy Astrophysical Survey
Borja Anguiano, Andres del Pino
The outskirts of nearby galaxies preserve long-lived signatures of hierarchical assembly and provide a fossil record of galaxy formation. J-ATLAS, the Javalambre Andromeda and Tria…

A. Hernán-Caballero, H. Vázquez Ramió, C. López-Sanjuan +20
We present spectral classifications and photometric redshifts for 79.2 million sources up to an r-band magnitude of 22 in Data Release 4 of the Javalambre Photometric Local Univers…
HSTPROMO Internal Proper Motion Kinematics of Dwarf Spheroidal Galaxies: I. Velocity Anisotropy and Dark Matter Cusp Slope of Draco
Eduardo Vitral, Roeland P. van der Marel, Sangmo Tony Sohn +8
We analyze four epochs of HST imaging over 18 years for the Draco dwarf spheroidal galaxy. We measure precise proper motions (PMs) for hundreds of stars and combine these with exis…
J-PLUS: Bayesian object classification with a strum of BANNJOS

With its 12 optical filters, the Javalambre-Photometric Local Universe Survey (J-PLUS) provides an unprecedented multicolor view of the local Universe. The third data release (DR3)…
BP3M: Bayesian Positions, Parallaxes, and Proper Motions derived from the Hubble Space Telescope and Gaia data
Kevin A. McKinnon, Andrés del Pino, Constance M. Rockosi +9
We present a hierarchical Bayesian pipeline, BP3M, that measures positions, parallaxes, and proper motions (PMs) for cross-matched sources between Hubble~Space~Telescope (HST) imag…

Alberto Manuel Martínez-García, Andrés del Pino, Ewa L. Łokas +2
We present a kinematic study of a thousand of dwarf satellites of MW/M31-like hosts from the IllustrisTNG50 simulation. Internal kinematics were derived for all the snapshots to ob…
J-PLUS DR3: Galaxy-Star-Quasar classification
R. von Marttens, V. Marra, M. Quartin +20
The Javalambre Photometric Local Universe Survey (J-PLUS) is a 12-band photometric survey using the 83-cm JAST telescope. Data Release 3 includes 47.4 million sources. J-PLUS DR3 o…
HubPUG: Proper Motions for Local Group Dwarfs observed with HST utilizing Gaia as a Reference Frame
Jack T. Warfield, Nitya Kallivayalil, Paul Zivick +6
We present the method behind HubPUG, a software tool built for recovering systemic proper motions (PMs) of Hubble Space Telescope (HST) fields with two epochs of observations by ut…
Kinematic Structure of the Large Magellanic Cloud Globular Cluster System from Gaia eDR3 and Hubble Space Telescope Proper Motions
Paul Bennet, Mayte Alfaro-Cuello, Andrés del Pino +3
We have determined bulk proper motions (PMs) for 31 LMC GCs from Gaia eDR3 and Hubble Space Telescope data using multiple independent analysis techniques. Combined with literature…
Tidally induced velocity gradients in the Milky Way dwarf spheroidal satellites
Alberto Manuel Martínez-García, Andrés del Pino, Antonio Aparicio
We present a kinematic study of six dwarf spheroidal galaxies (dSph) satellites of the Milky Way (MW), namely Carina, Draco, Fornax, Sculptor, Sextans, and Ursa Minor. We combine p…
GaiaHub: A method for combining data from the Gaia and Hubble space telescopes to derive improved proper motions for faint stars
Andrés del Pino, Mattia Libralato, Roeland P. van der Marel +6
We present GaiaHub, a publicly available tool that combines measurements with () archival images to derive proper motions (PMs). It increas…
Detection of Chemo-Kinematical Structures in Leo I
A. G. Alarcon Jara, M. Fellhauer, J. Simon +3
Context: A variety of formation models for dwarf spheroidal (dSph) galaxies have been proposed in the literature, but generally they have not been quantitatively compared with obse…
The structure of Andromeda II dwarf spheroidal galaxy
Andrés del Pino, Ewa L. Lokas, Sebastian L. Hidalgo +1
We analyze in detail the spatial distribution and kinematic properties of two different stellar populations in Andromeda II (And II) dwarf spheroidal galaxy. We obtained their deta…
Tidal origin of spiral arms in galaxies orbiting a cluster
Marcin Semczuk, Ewa L. Lokas, Andres del Pino
One of the scenarios for the formation of grand-design spiral arms in disky galaxies involves their interactions with a satellite or another galaxy. Here we consider another possib…
Formation of Andromeda II via a gas-rich major merger and an interaction with M31
