Search for new particles in events with one lepton and missing transverse momentum in pp collisions at s√ = 8 TeV with the ATLAS detector [PDF]

, 2014
This paper presents a search for new particles in events with one lepton (electron or muon) and missing transverse momentum using 20.3 fb−1 of proton-proton collision data at s√ = 8 TeV recorded by the ATLAS experiment at the Large Hadron Collider.

Exploring the correlation between dark matter, intracluster light, and globular cluster distribution in SMACS0723

, 2023
We present a free-form model of SMACS0723, the first cluster observed with JWST. This model does not make any strong assumptions on the distribution of mass (mostly made up of dark matter) in the cluster and we use it to study the possible correlation ...

Velocity and mass bias in the distribution of dark matter haloes [PDF]

Monthly Notices of the Royal Astronomical Society, 2014
The non-linear, scale-dependent bias in the mass distribution of galaxies and the underlying dark matter is a key systematic affecting the extraction of cosmological parameters from galaxy clustering. Using 95 million halos from the Millennium-XXL N-body simulation, we find that the mass bias is scale independent only for $k<0.1 h{\rm Mpc}^{-1 ...

The First Robust Evidence Showing a Dark Matter Density Spike Around the Supermassive Black Hole in OJ 287

The Astrophysical Journal Letters
Black hole dynamics suggests that dark matter would redistribute near a supermassive black hole (SMBH) to form a density spike. However, no direct evidence of a dark matter density spike around an SMBH has been identified.

Distribution of Dark Matter in Galaxies, In Search of the Dark Matter Particle

IOSR Journal of Applied Physics, 2014
A new theory called, the Dark Matter Flow Theory based on fluid mechanics concepts, has been given for the first time to derive the density of the dark matter and its distribution inside galaxies and beyond. Although the results are chocking, however they exhibit a high congruence with the measured observations of the velocity rotation curves of ...

The clustering of dark matter, haloes & galaxies [PDF]

, 2008
In this thesis I study the spatial distribution of galaxies, haloes and dark matter particles using a suite of state-of-art cosmological N-body simulations of the growth structure in the Universe.

Indirect Detection of Decaying Dark Matter with High Angular Resolution: The Case for Axion Search by IRCS on the Subaru Telescope

The Astrophysical Journal
Recent advances in photon detectors have provided exceptional sensitivities to dark matter with high angular resolution. Motivated by this, we present a detailed study of photon flux from dark matter decay in dwarf spheroidal galaxies (dSphs) by focusing

Baryonic distributions in the dark matter halo of NGC 5005 [PDF]

Monthly Notices of the Royal Astronomical Society, 2015
We present results from multiwavelength observations of the galaxy NGC5005. We use new neutral hydrogen (HI) observations from the Very Large Array to examine the neutral gas morphology and kinematics. We find an HI disk with a well-behaved flat rotation curve in the radial range 20\arcsec-140\arcsec.

The evolution of dark matter substructure [PDF]

, 2001
This thesis investigates the dynamical evolution of systems orbiting within deeper potentials. Initially we use a simple satellite-halo interaction to study the dynamical processes that act on orbiting systems and we compare these results to analytical ...
