Scant evidence for thawing quintessence

Physical Review D
New constraints on the expansion rate of the Universe seem to favor evolving dark energy in the form of thawing quintessence models, i.e., models for which a canonical, minimally coupled scalar field has, at late times, begun to evolve away from ...

The effect of coffee as a bio reductant in the synthesis of silver nano particles combined with laser photodynamics for bacteria inactivation.

Brazilian journal of biology = Revista brasleira de biologia
Silver nanoparticles (AgNPs) have gained significant attention in antimicrobial treatments due to their potent antibacterial properties and potential applications in combating antibiotic-resistant pathogens.

Tests of general relativity with GWTC-3

Physical Review D, 2021
The ever-increasing number of detections of gravitational waves (GWs) from compact binaries by the Advanced LIGO and Advanced Virgo detectors allows us to perform ever-more sensitive tests of general relativity (GR) in the dynamical and strong-field ...

Cosmology from CMB lensing and delensed EE power spectra using 2019–2020 SPT-3G polarization data

Physical Review D
From CMB polarization data alone we reconstruct the CMB lensing power spectrum, comparable in overall constraining power to previous temperature-based reconstructions, and an unlensed E-mode power spectrum.

Evidence for large baryonic feedback at low and intermediate redshifts from kinematic Sunyaev-Zel’dovich observations with ACT and DESI photometric galaxies

Physical Review D
Recent advances in cosmological observations have provided an unprecedented opportunity to investigate the distribution of baryons relative to the underlying matter. In this work, we show that the gas is more extended than the dark matter, and the amount

Dark Energy Survey: A 2.1% measurement of the angular baryonic acoustic oscillation scale at redshift zeff=

Physical Review D
We present the angular diameter distance measurement obtained with the Baryonic Acoustic Oscillation feature from galaxy clustering in the completed Dark Energy Survey, consisting of six years (Y6) of observations.

Developing a Spatially Explicit Forest Database for Planning and Carbon Stock Estimation: A GIS-based Approach in Rajgarh Forest Division of Sirmaur District, Himachal Pradesh, India

Journal of Geography Environment and Earth Science International
The conventional method of forest plan preparation cannot provide real-time forest inventory data, making planning inefficient. It struggles with data synthesis, retrieval, and reliability due to scattered sources.

XENONnT WIMP search: Signal and background modeling and statistical inference

Physical Review D
The XENONnT experiment searches for weakly interacting massive particle (WIMP) dark matter scattering off a xenon nucleus. In particular, XENONnT uses a dual-phase time projection chamber with a 5.9-ton liquid xenon target, detecting both scintillation
