In this review, we present the ongoing developments in bridging the gap between holography and experiments. To this end, we discuss information scrambling and models of quantum teleportation via Gao-Jafferis-Wall wormhole ...

The geodetic and frame-dragging effects are the direct consequences of the spacetime curvature near earth which can be probed from the Gravity probe B satellite. The satellite result matches quite well with Einstein's ...
Earth�s upper atmosphere over low latitudes is influenced by the equatorial electrodynamics. Its influence can also be modulated by the thermospheric winds. The effect of these two forces on the thermospheric neutral ...

We present results of three wide-band directed searches for continuous gravitational waves from 15 young supernova remnants in the first half of the third Advanced LIGO and Virgo observing run. We use three search pipelines ...
Heavy quark dynamics in an anisotropic QCD medium have been analyzed within the Fokker-Planck approach. Heavy quark drag force and momentum diffusion tensor have been decomposed by employing a general tensor basis for an ...

We report the reemergence of a new broadband emission through a detailed and systematic study of the multiwavelength spectral and temporal behavior of OJ 287 after its first-ever reported very high energy activity in 2017 ...
The Indian monsoon significantly influences the sea surface conditions in the northern Indian Ocean. Corals growing in shallow waters record such monsoon-induced surface water changes. The record of monsoon signatures in ...

We report on an all-sky search for continuous gravitational waves in the frequency band 20–2000 Hz and with a frequency time derivative in the range of [−1.0,+0.1]×10−8 Hz/s. Such a signal could be produced by a nearby, ...
Quantum aspects of black holes may have observational imprints on their absorption and emission spectrum. In this work, we consider the possibility of nonuniform area quantization and its effects on the phasing of a ...

The paper presents an analysis of multiwavelength data of two Lynds Bright Nebulae (LBNs), LBN 140.07+01.64 and LBN 140.77−1.42. The 1420-MHz continuum map reveals an extended Y-shaped feature (linear extent ∼3.7°), which ...
Ultralight axion like particles (ALPs) of mass m_a∈ (10 to the power of negative 21 eV–10 to the power of negative 21 eV) with axion decay constant fa∼ 10 to the power of 17 GeV can be candidates for fuzzy dark matter ...
Stable isotopic compositions of carbon (C) and nitrogen (N) in lake sediments have the potential to decipher natural and anthropogenic influences in a region, which has undergone significant cultural changes in the recent ...
Gaseous oxygen plays a vital role in driving the metabolism of living organisms and has multiple agricultural, medical, and technological applications. Different methods have been discovered to produce oxygen, including ...

The evidence of gravitational wave was first indirectly confirmed by the orbital period loss of Hulse-Taylor binary system which agrees well with the Einstein's general relativistic prediction. The perihelion precession ...

Flares are known to play an important role for the evolution of the atmospheres of young planets. In order to understand the evolution of planets, it is thus important to study the flare-activity of young stars. This is ...
