  • Morphologic and morphometric differences between gullies formed in different substrates on Mars: new insights into the gully formation processes 
    Sinha, Rishitosh K.; Ray, Dwijesh; Haas, Tjalling De; Conway, Susan J.; Noblet, Axel (European Geosciences Union, 2022-12)
    Martian gullies are kilometer-scale geologically young features with a source alcove, transportation channel, and depositional fan. On the walls of impact craters, these gullies typically incise into bedrock or surfaces ...

    Mazumder, Surasree; Chandra, Vinod; Das, Santosh K. (Cornell University Library, 2022-11)
    Heavy Quark (HQ) serves as an excellent probe to understand perturbative as well as non-perturbative aspects of hot deconfined medium of light quarks and gluons. Additionally, the existence of a strong magnetic field in ...

    Dobal, Richa et al. (Cornell University Library, 2022-11)
    We statistically validated a sample of hot Neptune candidates applying a two-step vetting technique using DAVE and TRICERATOPS. We performed a systematic validation of 250 transit-like events in the Transiting Exoplanet ...
