We present limits for the compactification scale in the theory of Large Extra Dimensions (LED) proposed by Arkani-Hamed, Dimopoulos, and Dvali. We use 11 months of data from the Fermi Large Area Telescope (Fermi-LAT) to set gamma ray flux limits for 6 gamma-ray faint neutron stars (NS). To set limits on LED we use the model of Hannestad and Raffelt (HR) that calculates the Kaluza-Klein (KK) graviton production in supernova cores and the large fraction subsequently gravitationally bound around… Expand
From diffuse extragalactic and galactic gamma-rays to limits on extra dimensions
We derive the maximum fraction of energy emitted in the form of massive (Kaluza–Klein) gravitons by core collapse supernovae, and the corresponding minimal extra-dimensional Planck mass M* in theExpand
Bounds on large extra dimensions from the simulation of black hole events at the LHC
A bstractIf large extra dimensions exist, the Planck scale may be as low as a TeV and microscopic black holes may be produced in high-energy particle collisions at this energy scale. We simulateExpand
Searches for new physics with the ATLAS experiment
The Standard Model has granted exquisite power to predict the behaviour of high-energy particle collisions. It is not, however, without conceptual and empirical weaknesses. Several theories have beenExpand
Exploring extra dimensions with scalar fields
This paper provides a pedagogical introduction to the physics of extra dimensions by examining the behavior of scalar fields in three landmark models: the ADD, Randall-Sundrum, and DGP spacetimes.Expand
Exploring extra dimensions with scalar waves
This paper provides a pedagogical introduction to the physics of extra dimensions focussing on the ADD, Randall-Sundrum and DGP models. In each of these models, the familiar particles and fields ofExpand
Dark Matter searches targeting Dwarf Spheroidal Galaxies with the Fermi Large Area Telescope
In this thesis I present our recent work on gamma-ray searches for dark matter with the Fermi Large Area Telescope (Fermi-LAT). We have targeted dwarf spheroidal galaxies since they are very dark mExpand
Searches for Dark Matter and Large Extra Dimensions in Monojet Final States with the ATLAS Experiment
The CERN Large Hadron Collider (LHC) is the most powerful particle ac- celerator ever built, in terms of luminosity and center-of-mass energy of the collisions. This thesis presents a search for DaExpand
Particle Phenomenology of Compact Extra Dimensions
This thesis is an investigation of the subject of extra dimensions in particle physics. In recent years, there has been a large interest in this subject. In particular, a number of models have beenExpand
Einstein’s Relativity as an a Priori Theory from the Perspective of Kantian Philosophy
Several points made by Immanuel Kant in Critique of Pure Reason regarding a priori synthetic and a priori analytic theories relating to geometry and mathematics are discussed. These points areExpand
Axion Gamma-Ray Signatures from Quark Matter in Neutron Stars
We present a theoretical model for detecting axions from neutron stars in a QCD phase of quark matter, in which the gamma-rays are produced from decaying axions. The axions would be produced from aExpand

Search for Large Extra Dimensions Based on Observations of Neutron Stars with the Fermi-LAT
According to the Large Extra Dimensions (LED) model of Arkani-Hamed, Dimopoulos, and Dvali (ADD), in addition to the (3+1) observed space-time dimensions, there exist n gravity-only spatialExpand
Supernova and neutron star limits on large extra dimensions reexamined
In theories with large extra dimensions, supernova ~SN! cores are powerful sources of Kaluza-Klein ~KK! gravitons. A large fraction of these massive particles are gravitationally retained by theExpand
New Supernova Limit on Large Extra Dimensions
If large extra dimensions exist in nature, supernova (SN) cores will emit large fluxes of Kaluza-Klein gravitons, producing a cosmic background of these particles with energies and masses up to aboutExpand
Gamma rays from the Galactic bulge and large extra dimensions.
TLDR
The limits on the radius of compactification of extra dimensions for a small number n of them are strengthened, or alternatively the fundamental scale of quantum gravity is considered, considering the gamma-ray emission of the whole population of neutron stars sitting in the Galactic bulge, instead of the closest member of this category.

New supernova limit on large extra dimensions: bounds on Kaluza-Klein graviton production.
TLDR
If large extra dimensions exist in nature, supernova (SN) cores will emit large fluxes of Kaluza-Klein gravitons, producing a cosmic background of these particles with energies and masses up to about 100 MeV which is well in excess of the observations if more than 0.5%-1% of the SN energy is emitted into the new channel.

Extra dimensions, SN1987a, and nucleon–nucleon scattering data
Abstract One of the strongest constraints on the existence of large, compact, “gravity-only” dimensions comes from SN1987a. If the rate of energy loss into these putative extra dimensions is tooExpand
Constraining dark matter models from a combined analysis of Milky Way satellites with the Fermi Large Area Telescope.
TLDR
This work presents a search for dark matter consisting of weakly interacting massive particles, applying a joint likelihood analysis to 10 satellite galaxies with 24 months of data of the Fermi Large Area Telescope, and is able to rule out models with the most generic cross section, using gamma rays.
