We present a pilot study using the Vera C. Rubin Observatory early alerts to verify RR Lyrae candidates in the Pan-STARRS1, the Dark Energy Survey, and the Next-Generation Virgo …
We leveraged reliable age and distance estimates from LAMOST-DR3 and APOGEE-DR17+AstroNN combined with Gaia data to perform a detailed analysis of the stellar age distribution in …
We study the velocity ellipsoids in an N-body$+$SPH (smooth particle hydrodynamics) simulation of a barred galaxy which forms a bar with a BP bulge. We focus on the 2D kinematics, …
RR Lyrae stars toward the Galactic bulge are used to investigate whether this old stellar population traces the Galactic bar. Although the bar is known to dominate the mass in the …
In this study, we have analyzed the spatial and transverse velocity distribution of RR Lyrae stars toward the Galactic bulge. We utilized data from OGLE-IV, Gaia, VVV, and VHS …
From the TNG50 cosmological simulation we build a sample of 191 well-resolved barred galaxies with stellar mass $\mbox{$\log (M_{\star }/\mathrm{M}_{\odot })$}\gt 10$ at z = 0. We …
Simulations of barred galaxies give us insights into bar-driven internal evolution that separates stellar populations spatially and kinematically but requires sufficient resolution …
We use an N-body+smoothed particle hydrodynamics simulation of an isolated barred galaxy to study the age dependence of bulge longitudinal proper motion (μl) rotation curves. We …
