Classification of Wolf Rayet stars using Ensemble-based Machine Learning algorithms
Subhajit Kar, Rajorshi Bhattacharya, Ramkrishna Das +2
We develop a robust Machine Learning classifier model utilizing the eXtreme-Gradient Boosting (XGB) algorithm for improved classification of Galactic Wolf-Rayet (WR) stars based on…
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…
Carbon- and Oxygen-rich Asymptotic Giant Branch (AGB) stars in the Bulge Asymmetries and Dynamical Evolution (BAaDE) survey
Megan O. Lewis, Ylva M. Pihlström, Loránt O. Sjouwerman +2
Detections of SiO masers from the Bulge Asymmetries and Dynamical Evolution (BAaDE) survey more tightly define the region where Oxygen-rich (O) Asymptotic Giant Branch (AGB) stars…
SiO Masers in the Galactic Bulge and Disk: Kinematics from the BAaDE Survey
A. C. Trapp, R. M. Rich, M. R. Morris +4
We present the first results from the BAaDE (Bulge Asymmetries and Dynamic Evolution) survey. Though only a subset of the complete survey (2700 out of 20000 final sourc…
44 GHz Class I Methanol (CHOH) Maser Survey in the Galactic Center
Bridget McEwen, Loránt Sjouwerman, Ylva Pihlström
We report on a large 44 GHz ( A) methanol (CHOH) maser survey of the Galactic Center (GC). The Karl G. Jansky Very Large Array was used to search for CHOH mase…
NH(3,3) and CHOH near Supernova Remnants: GBT and VLA Observations
Bridget McEwen, Ylva Pihlström, Loránt Sjouwerman
We report on Green Bank Telescope 23.87 GHz NH(3,3), emission observations in five supernova remnants interacting with molecular clouds (G1.40.1, IC443, W44, W51C, and G5.7$…
