Modelling Supernova Explosions in Disk Galaxy Simulations

Dhruv Kumar

We present an enhanced model for disk galaxy simulations that better incorporates supernova (SN) feedback in a non-uniform interstellar medium (ISM). Current models often oversimplify ISM structure by considering a homogeneous medium, compromising the accuracy of energy and momentum transfer from supernova …

The Indian Pulsar Timing Array data release 2: I. Dataset and timing analysis

Prerna Rana, Pratik Tarafdar, K. Nobleson, C. Dwivedi et autres

Abstract The Indian Pulsar Timing Array (InPTA) employs unique features of the upgraded Giant Metrewave Radio Telescope (uGMRT) to monitor dozens of the International Pulsar Timing Array (IPTA) millisecond pulsars (MSPs), simultaneously in the 300–500 MHz and the 1260–1460 MHz bands. This …

Performance of a Five-Layer ANN Model for Earthquake Magnitude Prediction and Spatial Risk Mapping in Turkey

Saptadeep Biswas, Dhruv Kumar, Murat Nas, Mustafa Softa et autres

Turkey faces significant seismic risks, necessitating accurate earthquake forecasting for effective disaster preparedness. This study employs advanced Artificial Neural Networks (ANN) to predict earthquake magnitudes and assess risks specific to Turkey. Focusing on a distinct segment of the USGS earthquake catalogue from …

VaTEST III: Validation of eight potential super-earths from TESS data

Priyashkumar Mistry, Aniket Prasad, Mousam Maity, Kamlesh Pathak et autres

Abstract NASA’s all-sky survey mission, the Transiting Exoplanet Survey Satellite (TESS), is specifically engineered to detect exoplanets that transit bright stars. Thus far, TESS has successfully identified approximately 400 transiting exoplanets, in addition to roughly 6 000 candidate exoplanets pending confirmation. In …

Early Universe Cosmology in The Light of Hubble Tension

Dhruv Kumar

Our comprehension of fundamental cosmological principles hinges on a thorough understanding of the early universe. The Lambda Cold Dark Matter (ΛCDM) model has emerged as a valuable framework for elucidating various cosmic phenomena, uniting a cosmological constant (Λ) with cold dark matter …

VaTEST. II. Statistical Validation of 11 TESS-detected Exoplanets Orbiting K-type Stars

Priyashkumar Mistry, Kamlesh Pathak, Aniket Prasad, Georgios Lekkas et autres

Abstract NASA’s Transiting Exoplanet Survey Satellite (TESS) is an all-sky survey mission designed to find transiting exoplanets orbiting nearby bright stars. It has identified more than 329 transiting exoplanets, and almost 6000 candidates remain unvalidated. In this manuscript, we discuss the findings …

Prediction of earthquake magnitude and seismic vulnerability mapping using artificial intelligence techniques: a case study of Turkey

Saptadeep Biswas, Dhruv Kumar, Uttam Kumar Bera

Abstract Earthquake threats can result in fatalities, property destruction, and other cascading effects. Since it is nearly impossible to prevent earthquakes, anticipating the location of future earthquakes and figuring out their likelihood could be very helpful in reducing the seismic threat. In …
