Peanut-shaped metallicity distributions in bulges of edge-on galaxies: the case of NGC 4710
Oscar A. Gonzalez, Victor P. Debattista, Melissa Ness +2
Bulges of edge-on galaxies are often boxy/peanut-shaped (B/PS), and unsharp masks reveal the presence of an X shape. Simulations show that these shapes can be produced by dynamical…
The GIRAFFE Inner Bulge Survey (GIBS) III. Metallicity distributions and kinematics of 26 Galactic bulge fields
M. Zoccali, S. Vasquez, O. A. Gonzalez +9
Several recent studies have demonstrated that the Galactic bulge hosts two components with different mean metallicities, and possibly different spatial distribution and kinematics.…
Discovery of RR Lyrae Stars in the Nuclear Bulge of the Milky Way
D. Minniti, R. Contreras Ramos, M. Zoccali +4
Galactic nuclei, like the one of the Milky Way, are extreme places with high stellar densities and, in most cases, hosting a supermassive black hole. One of the scenarios proposed…
Regaining the FORS: making optical ground-based transmission spectroscopy of exoplanets with VLT+FORS2 possible again
Henri M. J. Boffin, Elyar Sedaghati, Guillaume Blanchard +10
Transmission spectroscopy facilitates the detection of molecules and/or clouds in the atmospheres of exoplanets. Such studies rely heavily on space-based or large ground-based obse…
Mapping the outer bulge with RRab stars from the VVV Survey
F. Gran, D. Minniti, R. K. Saito +8
The VISTA Variables in the Vía Láctea (VVV) is a near-IR time-domain survey of the Galactic bulge and southern plane. One of the main goals of this survey is to reveal the 3D struc…
Comparing the properties of the X-shaped bulges of NGC 4710 and the Milky Way with MUSE
O. A. Gonzalez, D. A. Gadotti, V. P. Debattista +6
We used the new ESO VLT instrument MUSE to obtain spectral and imaging coverage of NGC 4710. The wide area and excellent sampling of the MUSE integral field spectrograph allows us…
