A Pilot Study to Verify the RR Lyrae Candidates with Vera C. Rubin Observatory Early Alerts
Chow-Choong Ngeow, Anupam Bhardwaj, Sarang Shah +2
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 Cl…
The edge of the Milky Way's star-forming disc: Evidence from a 'U-shaped' stellar age profile
Karl Fiteni, Stuart Robert Anderson, Victor. P. Debattista +7
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…
The Galactic Bulge exploration V.: The secular spherical and X-shaped Milky Way bulge
Z. Prudil, V. P. Debattista, L. Beraldo e Silva +9
In this work, we derive systemic velocities and subsequently orbits for 8456 RR~Lyrae stars. We identify interlopers from other Milky Way (MW) structures, which amount to 22 percen…
The chemical and spatial variations of the bulge's velocity ellipsoids
Luis M. San Martin Fernandez, Steven Gough-Kelly, Victor P. Debattista +4
We study the velocity ellipsoids in an -bodySPH simulation of a barred galaxy which forms a bar with a BP bulge. We focus on the 2D kinematics, and quantify the velocity elli…
The Galactic Bulge exploration IV.: RR~Lyrae stars as traces of the Galactic bar -- 3D and 5D analysis, extinction variation
Z. Prudil, A. Kunder, L. Beraldo e Silva +10
We created new reddening maps and derived new extinction laws from visual to near-infrared passbands using improved RR~Lyrae period-absolute magnitude-metallicity relations, thus e…
Synergies between Roman Galactic Plane Survey and other major surveys
Katarzyna Kruszyńska, Rachel A. Street, Steven Gough-Kelly +15
Nancy Grace Roman Space Telescope will revolutionize our understanding of the Galactic Bulge with its Galactic Bulge Time Domain survey. At the same time, Rubin Observatories's Leg…
Maximizing science return by coordinating the survey strategies of Roman with Rubin, and other major facilities
R. A. Street, S. Gough-Kelly, C. Lam +13
[Abridged] The Nancy Grace Roman Space Telescope will be one of several flagship survey facilities operating over the next decade starting 2025. The deep near-IR imaging that…
The interplay between accretion, galaxy downsizing and the formation of box/peanut bulges in TNG50
Stuart Robert Anderson, Steven Gough-Kelly, Victor P. Debattista +6
From the TNG50 cosmological simulation we build a sample of 191 well-resolved barred galaxies with a stellar mass at . We search for box/peanut bulges (BPs…
Predicted Trends in Milky Way Bulge Proper Motion Rotation Curves: future Prospects for HST and LSST
Steven Gough-Kelly, Victor P. Debattista, William I. Clarkson +5
We use an -body+smoothed particle hydrodynamics simulation of an isolated barred galaxy to study the age dependence of bulge longitudinal proper motion () rotation curves.…
