Dark Matter decay and annihilation in the Local Universe: CLUES from Fermi [PDF]
, 2011 We present all-sky simulated Fermi maps of gamma-rays from dark matter decay and annihilation in the Local Universe. The dark matter distribution is obtained from a constrained cosmological simulation of the neighboring large-scale structure provided by ...

Toward (finally!) ruling out Z and Higgs mediated dark matter models [PDF]
, 2016 In recent years, direct detection, indirect detection, and collider experiments have placed increasingly stringent constraints on particle dark matter, exploring much of the parameter space associated with the WIMP paradigm.

Dark matter models and direct detection
Proceedings of Theoretical Advanced Study Institute Summer School 2018 "Theory in an Era of Data" — PoS(TASI2018), 2019 These lectures provide an introduction to models and direct detection of dark matter. We summarize the general features and motivations for candidates in the full dark matter mass range, and then restrict to the keV-TeV mass window.

Simplified models vs. effective field theory approaches in dark matter searches [PDF]
, 2016 In this review we discuss and compare the usage of simplified models and Effective Field Theory (EFT) approaches in dark matter searches. We provide a state of the art description on the subject of EFTs and simplified models, especially in the context of

WIMP and FIMP dark matter in singlet-triplet fermionic model
Journal of High Energy Physics, 2022 We present an extension of the SM involving three triplet fermions, one triplet scalar and one singlet fermion, which can explain both neutrino masses and dark matter.

Review of strongly-coupled composite dark matter models and lattice simulations [PDF]
, 2016 We review models of new physics in which dark matter arises as a composite bound state from a confining strongly-coupled non-Abelian gauge theory. We discuss several qualitatively distinct classes of composite candidates, including dark mesons, dark ...

Non-cold dark matter from primordial black hole evaporation [PDF]
Journal of Cosmology and Astroparticle Physics, 2020 Dark matter coupled solely gravitationally can be produced through the decay of primordial black holes in the early universe. If the dark matter is lighter than the initial black hole temperature, it could be warm enough to be subject to structure ...

Imprints of dark matter on black hole shadows using spherical accretions [PDF]
The European Physical Journal C, 2020 We study the possibility of identifying dark matter in the galactic center from the physical properties of the electromagnetic radiation emitted from an optically-thin disk region around a static and spherically symmetric black hole.

The Growth of Structure in Interacting Dark Energy Models [PDF]
, 2009 If dark energy interacts with dark matter, there is a change in the background evolution of the universe, since the dark matter density no longer evolves as a^{-3}. In addition, the non-gravitational interaction affects the growth of structure.

Brief History of Ultra-light Scalar Dark Matter Models [PDF]
, 2017 This is a review on the brief history of the scalar field dark matter model also known as fuzzy dark matter, BEC dark matter, wave dark matter, or ultra-light axion.
