RR Lyrae binary systems in the Galactic bulge

EPJ Web of Conferences, 2017
The possibility of a direct mass measurement of RR Lyrae variable stars in binary systems has remained elusive for many years, due to the apparent paucity of such systems.

Einstein@Home Searches for Gamma-Ray Pulsars in the Inner Galaxy

The Astrophysical Journal
The Fermi Large Area Telescope (LAT) has revealed a mysterious extended excess of GeV gamma-ray emission around the Galactic Center (GC), which can potentially be explained by unresolved emission from a population of pulsars, particularly millisecond ...

A Breakdown of the Black Hole–Bulge Mass Relation in Local Active Galaxies

The Astrophysical Journal
We investigate the relation between black hole (BH) mass and bulge stellar mass for a sample of 117 local ( z ∼ 0) galaxies hosting low-luminosity, broad-line active galactic nuclei (AGNs).

Tracing Back a Second-generation Star Stripped from Terzan 5 by the Galactic Bar

The Astrophysical Journal Letters
The Galactic bulge hosts the Milky Way’s oldest stars, possibly coming from disrupted globular clusters (GCs) or the bulge’s primordial building blocks, making these stars witnesses to the Galaxy’s early chemical enrichment.

Tracing the Galactic Origins of Selected Four G-type Stars in the Solar Neighborhood

The Astronomical Journal
We present a multimethod investigation of four metal-poor G-type main-sequence stars to resolve their Galactic origins. By combining high-resolution spectroscopy from PolarBase, photometric/astrometric data from Gaia DR3, and spectral energy distribution
