If a subdominant component of dark matter (DM) interacts via long-range dark force carriers it may cool and collapse to form complex structures within the Milky Way galaxy, such as a rotating dark disk. This scenario was proposed recently and termed ''Double-Disk Dark Matter'' (DDDM). In this paper we consider the possibility that DDDM remains in a cosmologically long-lived excited state and can scatter exothermically on nuclei (ExoDDDM). We investigate the current status of ExoDDDM direct…

Direct and indirect detection of dissipative dark matter
We study the constraints from direct detection and solar capture on dark matter scenarios with a subdominant dissipative component. This dissipative dark matter component in general has both a
Assuming the existence of a primordial asymmetry in the dark sector, we study how long-range dark matter (DM)–baryon interactions, induced by the kinetic mixing of a new U(1) gauge boson and a
Structure formation and exotic compact objects in a dissipative dark sector
We present the complete history of structure formation in a simple dissipative dark-sector model. The model has only two particles: a dark electron, which is a subdominant component of dark matter,

Dark matter haloes in the multicomponent model – I. Substructure
Multicomponent dark matter with self-interactions, which allows for inter-conversions of species into one another, is a promising paradigm that is known to successfully and simultaneously resolve
Nonthermal production of dark radiation and dark matter
A bstractDark matter may be coupled to dark radiation: light degrees of freedom that mediate forces between dark sector particles. Cosmological constraints favor dark radiation that is colder than
Constraining a Thin Dark Matter Disk with Gaia.
The first data release from the Gaia space observatory is used to search for a dark disk via its effect on stellar kinematics in the Milky Way, and new limits disfavor the presence of a thin dark matter disk.
Composite dark matter and direct-search experiments
The results of the direct searches for dark matter are reinterpreted in the framework of composite dark matter, i.e. dark matter particles that form neutral bound states, generically called “dark
We consider the cosmological consequences if a small fraction ( f ≲ 0.1 ?> ) of the dark matter is ultra-strongly self-interacting, with an elastic self-interaction cross section per unit mass &sgr;
Cooling in a dissipative dark sector
The possibility of a subdominant component of dark matter dissipating energy could lead to dramatic new phenomenology such as the formation of a dark disk. One rigorous way to assess this possibility


Exothermic dark matter
We propose a novel mechanism for dark matter to explain the observed annual modulation signal at DAMA/LIBRA which avoids existing constraints from every other dark matter direct detection experiment
Massive satellite accretions onto early galactic disks can lead to the deposition of dark matter in disk-like configurations that co-rotate with the galaxy. This phenomenon has potentially dramatic
Thin, thick and dark discs in ΛCDM
In acold dark matter (� CDM) cosmology, the Milky Way accretes satellites into the stellar disc. We use cosmological simulations to assess the frequency of near disc plane and higher inclination
Dark matter and dark radiation
We explore the feasibility and astrophysical consequences of a new long-range U(1) gauge field ("dark electromagnetism") that couples only to dark matter, not to the Standard Model. The dark matter
Dark matter direct detection signals inferred from a cosmological N-body simulation with baryons
We extract at redshift z = 0 a Milky Way sized object including gas, stars and dark matter (DM) from a recent, high-resolution cosmological N-body simulation with baryons. Its resolution is

Inelastic dark matter, non-standard halos and the DAMA/LIBRA results
The DAMA collaboration have claimed to detect particle dark matter (DM) via an annual modulation in their observed recoil event rate. This appears to be in strong disagreement with the null results
Asymmetric Dark Matter and Dark Radiation
Asymmetric Dark Matter (ADM) models invoke a particle-antiparticle asymmetry, similar to the one observed in the Baryon sector, to account for the Dark Matter (DM) abundance. Both asymmetries are
