  • Can Hubble tension be eased by invoking a finite range for gravity? 
    Rebecca, Louise; Sivaram, C; Sebastian, Dominic; Kenath, Arun (World Scientific Publishing, 2024-06)
    The estimation of the Hubble constant in the past few decades has increasingly become more accurate with the advancement of new techniques. However, its value seems to depend on the epoch at which the measurements are made. ...
  • High-resolution spectral analysis of three high-latitude carbon stars 
    Meenakshi, P; Dutta, Debasish; Goswami, A; Kartha, Sreeja S (Cambridge University Press on behalf of Astronomical Society of Australia, 2025-04)
    We present the results of a detailed high-resolution spectroscopic analysis (SUBARU/HDS spectra, R ∼50,000) of three faint high-latitude carbon stars HE 1104 − 0957, HE 1205 − 0521, and HE 1244 − 3036. Our estimated ...
