We present the results of the study of visible (UBVRIZ) intra-night microvariability in the blazar OJ 287. Useful observations (at least four integrations in a...
The Mid-Infrared Emission of Seyfert Galaxies: A New Analysis of ISOCAM Data
We present mid-infrared data of a sample of 57 AGNs obtained with the instrument ISOCAM on board the Infrared Space Observatory (ISO) satellite. The images were...
The Milky Way bar and bulge revealed by APOGEE and Gaia EDR3
We investigate the inner regions of the Milky Way using data from APOGEE and Gaia EDR3. Our inner Galactic sample has more than 26 500 stars within |X Gal|< 5...
The Milky Way bar pattern speed using Hercules and Gaia DR3
The distribution of moving groups in the solar neighbourhood has been used to constrain dynamical properties of the Milky Way for decades. The kinematic...
The Milky Way Tomography with SDSS. III. Stellar Kinematics
We study Milky Way kinematics using a sample of 18.8 million main-sequence stars with r 20 and proper-motion measurements derived from Sloan Digital Sky Survey...
The Milky Way's bulge star formation history as constrained from its bimodal chemical abundance distribution
We conduct a quantitative analysis of the star formation history (SFH) of the Milky Way's (MW) bulge by exploiting the constraining power of its stellar [Fe/H]...
