Comparing the Detectability of the Baryon Acoustic Oscillation through Gravitational-Wave Autocorrelation and Cross-Correlation with Galaxies
Gautam Bhuyan, Tathagata Ghosh, Surhud More
The amplitude and waveform shape of gravitational wave radiation from compact binary mergers enable a direct measurement of the luminosity distance to these events, making them \te…
The effect of metallicity on the Leavitt Law using phase-dependent properties of classical Cepheids
Gautam Bhuyan, Shashi Kanbur, Sukanta Deb +5
The absolute calibration of period-luminosity (PL) relations of Cepheids in the Milky Way (MW) and its nearby galaxies has been a cornerstone in determining extragalactic distances…
Multiwavelength study of observed and predicted pulsation properties of First overtone Cepheids in the Magellanic Clouds
Kerdaris Kurbah, Shashi M. Kanbur, Sukanta Deb +4
We present a detailed analysis of the light curves and pulsation properties of First Overtone (FO) Cepheids in the Magellanic Clouds (MCs) obtained using observations and predictio…
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…
