Nowadays, remarkable attention has been paid to exploring the materials containing rare earth elements because of their practical technological applications. Rare earth doped phosphors with excellent luminescent properties ...

The Littlest Seesaw model is a very well motivated dark matter model. Here we consider an extension of that model with an additional scalar and an additional fermionic particle under the freeze-in scenario. Formation of ...

Clouds more massive than about 105 M⊙ are potential sites of massive cluster formation. Studying the properties of such clouds in the early stages of their evolution offers an opportunity to test various cluster formation ...

We present an estimation and analysis of Near Infrared (NIR) background for the astronomical site at Mount Abu. Mount Abu Observatory is situated at Gurushikhar, Rajasthan, India, operated by the Physical Research Laboratory. ...

We present a novel Hall magnetohydrodynamics (HMHD) numerical simulation of a three-dimensional (3D) magnetic flux rope (MFR)-generated by magnetic reconnections from an initial 3D bipolar sheared field. Magnetic reconnections ...

The circumnuclear material around active galactic nuclei (AGNs) is one of the essential components of the obscuration-based unification model. However, our understanding of the circumnuclear material in terms of its ...

We consider a timelike geodesic congruence in the presence of perturbative quantum fluctuations of the spacetime metric. We calculate the change in the volume of a bundle of geodesics due to such fluctuations and thereby ...

Asian rivers, covering ∼29% of the global river surface area, account for ∼35% of the global freshwater discharge and transport a disproportionately large flux (∼70%) of total suspended matter to the oceans. With recent ...

In this paper, we explore the collider phenomenology of charged Higgs bosons in the context of a generic Beyond Standard Model scenario with extended gauge and scalar sectors. In such scenarios, the charged Higgs boson can ...

We present the discovery of a transiting massive giant planet around TOI-4603, a sub-giant F-type star from NASA’s Transiting Exoplanet Survey Satellite (TESS). The newly discovered planet has a radius of 1.042-0.035+0.038 RJ ...
