Geometry of the LMC based on multi-phase analysis of multi-wavelength Cepheid light curves using OGLE-IV and Gaia DR3 data
Gautam Bhuyan, Sukanta Deb, Shashi M. Kanbur +3
The period-luminosity (PL) relation of Cepheids in the Large Magellanic Cloud (LMC) plays a pivotal role in extra-galactic distance measurement and the determination of the Hubble…
Photometric Metallicity and Distance for the Two RR Lyrae in Segue II and Ursa Major II Dwarf Galaxies Based on Multi-Band Light-Curves
Chow-Choong Ngeow, Anupam Bhardwaj
Multi-band light curves of two RR Lyrae variables in Segue II and Ursa Major II ultra-faint dwarf (UFD) galaxies were collected from near simultaneous observations using the Lulin…
A multiphase study of classical Cepheids in the Magellanic Clouds- Models and Observations
Kerdaris Kurbah, Shashi M. Kanbur, Sukanta Deb +5
This work presents the study of multiphase relations of classical Cepheids in the Magellanic Clouds for short periods (log P < 1) and long periods (log P > 1). From the analysis, i…
High-resolution Spectroscopic Metallicities of Milky Way Cepheid Standards and their impact on the Leavitt Law and the Hubble constant
Anupam Bhardwaj, Adam G. Riess, Giovanni Catanzaro +10
Milky Way Cepheid variables with accurate {\it Hubble Space Telescope} photometry have been established as standards for primary calibration of the cosmic distance ladder to achiev…
Zwicky Transient Facility and Globular Clusters: the gr-Band Period-Luminosity Relations for Mira Variables at Maximum Light and Their Applications to Local Galaxies
Chow-Choong Ngeow, Jia-Yu Ou, Anupam Bhardwaj +3
Based on 14 Miras located in 7 globular clusters, we derived the first gr-band period-luminosity (PL) at maximum light for the large-amplitude Mira variables using the multi-year l…
Period-Luminosity-Metallicity relations for Classical Pulsators at Near-infrared Wavelengths
Anupam Bhardwaj
Classical pulsating stars such as Cepheid and RR Lyrae variables exhibit well-defined Period-Luminosity relations at near-infrared wavelengths. Despite their extensive use as stell…
