Mapping the Inner Milky Way with Infrared-Derived Distances to AGB Stars
Rajorshi Bhattacharya, Subhajit Kar, Loránt O. Sjouwerman +1
The structure and evolution of the Milky Way (MW) can be traced with distance estimates to the evolved stellar populations in the inner galactic region. However, direct astrometric…
The Milky Way bar potential constrained by the kinematics of SiO maser stars in BAaDE Survey
Tian-Ye Xia, Juntai Shen, Zhi Li +5
We introduce a novel method that utilizes the longitude-velocity (l-v) envelope to constrain the Milky Way (MW) bar potential. Previous work (Habing 2016) used the l-v diagram to e…
Distance estimate method for Asymptotic Giant Branch stars using Infrared Spectral Energy Distributions
Rajorshi Bhattacharya, Brandon M. Medina, Ylva M. Pihlström +8
We present a method to estimate distances to Asymptotic Giant Branch (AGB) stars in the Galaxy, using spectral energy distributions (SEDs) in the near- and mid-infrared. By assumin…
Long-period maser-bearing Miras in the Galactic center: period-luminosity relations and extinction estimates
M. O. Lewis, R. Bhattacharya, L. O. Sjouwerman +5
We establish a sample of 370 Mira variables that are likely near the Galactic center (GC). The sources have been selected from the OGLE and BAaDE surveys based on their sky coordin…
Searching for Radio Outflows from M31* with VLBI Observations
Sijia Peng, Zhiyuan Li, Lorant O. Sjouwerman +3
As one of the nearest and most dormant supermassive black holes (SMBHs), M31* provides a rare but promising opportunity for studying the physics of black hole accretion and feedbac…
Characterizing the Evolved Stellar Population in the Galactic Foreground I: Bolometric Magnitudes, Spatial Distribution and P-L Relations
Luis Henry Quiroga-Nuñez, Huib Jan van Langevelde, Loránt O. Sjouwerman +6
Radio campaigns using maser stellar beacons have provided crucial information to characterize Galactic stellar populations. Currently, the Bulge Asymmetries and Dynamical Evolution…
