Searching for new Hypervelocity Stars with Gaia DR3 and VLT/FORS2 Spectroscopy
Julio A. Carballo-Bello, Pau Ramos, Jesús M. Corral-Santana +5
Hypervelocity stars are unique objects moving through the Milky Way at speeds exceeding the local escape velocity, providing valuable insights into the Galactic gravitational poten…
The VISTA Variables in the Vía Láctea eXtended (VVVX) ESO public survey: Completion of the observations and legacy
R. K. Saito, M. Hempel, J. Alonso-García +143
The ESO public survey VISTA Variables in the Vía Láctea (VVV) surveyed the inner Galactic bulge and the adjacent southern Galactic disk from . Upon its conclusion, the c…
A revised view of the Canis Major stellar overdensity with DECam and Gaia: new evidence of a stellar warp of blue stars
Julio A. Carballo-Bello, David Martínez-Delgado, Jesús M. Corral-Santana +4
We present DECam imaging combined with Gaia DR2 data to study the Canis Major overdensity. The presence of the so-called Blue Plume stars in a low-pollution area of the color-magni…
Stellar streams around the Magellanic Clouds in 4D
Camila Navarrete, Vasily Belokurov, Márcio Catelan +7
We carried out a spectroscopic follow-up program of the four new stellar stream candidates detected by Belokurov & Koposov (2016) in the outskirts of the Large Magellanic Cloud (LM…
The globular cluster NGC7492 and the Sagittarius tidal stream: together but unmixed
Julio A. Carballo-Bello, Jesús M. Corral-Santana, Márcio Catelan +7
We have derived from VIMOS spectroscopy the radial velocities for a sample of 71 stars selected from CFHT/Megacam photometry around the Galactic globular cluster NGC7492. In the re…
The southern leading and trailing wraps of the Sagittarius tidal stream around the globular cluster Whiting1
Julio A. Carballo-Bello, Jesus M. Corral-Santana, David Martinez-Delgado +6
We present a study of the kinematics of 101 stars observed with VIMOS around Whiting1, a globular cluster embedded in the Sagittarius tidal stream. The obtained velocity distributi…
A search for stellar tidal debris of defunct dwarf galaxies around globular clusters in the inner Galactic halo
Julio A. Carballo-Bello, Antonio Sollima, David Martinez-Delgado +5
In the hierarchical formation scenario in which the outer halo of the Milky Way is the result of the continuous accretion of low-mass galaxies, a fraction of the Galactic globular…
A Black Hole Nova Obscured by an Inner Disk Torus
J. M. Corral-Santana, J. Casares, T. Muñoz-Darias +5
Stellar-mass black holes (BHs) are mostly found in X-ray transients, a subclass of X-ray binaries that exhibit violent outbursts. None of the 50 Galactic BHs known show eclipses, w…
A first catalogue of automatically selected UV-excess sources from the UVEX survey
Kars Verbeek, Eelco de Groot, Paul J. Groot +10
We present the first catalogue of point-source UV-excess sources selected from the UVEX survey. UVEX images the Northern Galactic Plane in the U, g, r and HeI5875 bands in the Gala…
New Optical Results on gamma-ray Binaries
J. Casares, J. M. Corral-Santana, A. Herrero +9
We present new optical spectroscopy of the gamma-ray binary LS 5039. Our data show evidence for sub-orbital modulation in the radial velocities with amplitude ~7 km/s and period ~P…
The UV-Excess Survey of the Northern Galactic Plane (UVEX)
Paul J. Groot, K. Verbeek, R. Greimel +41
The UV-Excess Survey of the Northern Galactic Plane images a 10x185 degree wide band, centered on the Galactic Equator using the 2.5m Isaac Newton Telescope in four bands (U,g,r,He…
