Role of density profile of sub-GeV dark matter in the properties of dark matter admixed quark stars with Bayesian analysis of dark-NJL model
Debashree Sen, Atanu Guha, Jong-Chul Park
We investigate the structural and oscillation properties of dark matter (DM) admixed strange quark stars (DMSQSs). The strange quark matter (SQM) is described with the well-known N…
A congruous approach with realistic cross section towards limiting sub-GeV dark matter from LUX-ZEPLIN
Atanu Guha, Jong-Chul Park
We present constraints on sub-GeV dark matter (DM) through the mechanism of being boosted by cosmic rays (CRs). We utilize the nuclear recoil data from the LUX-ZEPLIN (LZ) experime…
Non-radial oscillations of hadronic neutron stars, quark stars, and hybrid stars : Calculation of , , and mode frequencies
Atanu Guha, Debashree Sen, Chang Ho Hyun
The composition and equation of state (EoS) of dense matter relevant to compact stars are quite inconclusive. However, certain observational constraints on the structural propertie…
Impact of dark boson mediated feeble interaction between dark matter and hadronic matter on -mode oscillation of neutron stars
Debashree Sen, Atanu Guha
We studied the possible presence of dark matter (DM) in neutron stars (NSs) and the structural properties of the DM admixed NSs (DMANSs) in one of our recent works \cite{Guha:2024p…
Effects of dark boson mediated feeble interaction between dark matter (DM) and quark matter on -mode oscillation of DM admixed quark stars
O. P. Jyothilakshmi, Lakshmi J. Naik, Debashree Sen +2
We investigate the behavior of the prominent non-radial fundamental -mode oscillations of dark matter (DM) admixed strange quark stars (DMSQSs), by adopting an equation of state…

Debashree Sen, Atanu Guha
Considering four known pulsars J1906+0746, J1933-6211, J2043+1711 and the Vela pulsar, we study the scenario of dark matter (DM) capture in neutron stars (NSs). For the purpose we…
Constraints on cosmic-ray boosted dark matter with realistic cross section
Atanu Guha, Jong-Chul Park
Sub-MeV cold dark-matter particles are unable to produce electronic recoil in conventional dark-matter direct detection experiments such as XENONnT and LUX-ZEPLIN above the detecto…
Vector dark boson mediated feeble interaction between fermionic dark matter and strange quark matter in quark stars
Debashree Sen, Atanu Guha
We study the structural properties like the gravitational mass, radius and tidal deformability of dark matter (DM) admixed strange quark stars (SQSs). For the purpose we consider t…
Bounds on boosted dark matter from direct detection: The role of energy-dependent cross sections
Debjyoti Bardhan, Supritha Bhowmick, Diptimoy Ghosh +2
The recoil threshold of Direct Detection experiments limits the mass range of Dark Matter (DM) particles that can be detected, with most DD experiments being blind to sub-MeV DM pa…
EFT analysis of leptophilic dark matter at future electron-positron colliders in the mono-photon and mono- channels
Saumyen Kundu, Atanu Guha, Prasanta Kumar Das +1
We consider the possibility that dark matter (DM) only interacts with the Standard Model leptons, but not quarks at tree level, and analyze the future lepton collider prospects of…
