Axion Star Explosions: A New Source for Axion Indirect Detection
/ Escudero, Miguel (CERN) ; Pooni, Charis Kaur (King's Coll. London) ; Fairbairn, Malcolm (King's Coll. London) ; Blas, Diego (Barcelona, Autonoma U. ; Barcelona, IFAE) ; Du, Xiaolong (Carnegie Inst. Observ. ; UCLA) ; Marsh, David J.E. (King's Coll. London)
If dark matter is composed of axions, then axion stars form in the cores of dark matter halos. These stars are unstable above a critical mass, decaying to radio photons that heat the intergalactic medium, offering a new channel for axion indirect detection. [...]

Cold atoms in space: community workshop summary and proposed road-map
/ Alonso, Iván (Balearic Islands U.) ; Alpigiani, Cristiano (Washington U., Seattle) ; Altschul, Brett (South Carolina U.) ; Araújo, Henrique (Imperial Coll., London) ; Arduini, Gianluigi (CERN) ; Arlt, Jan (Aarhus U.) ; Badurina, Leonardo (King's Coll. London) ; Balaž, Antun (Belgrade, Inst. Phys.) ; Bandarupally, Satvika (Florence U. ; INFN, Florence) ; Barish, Barry C. (LIGO Lab., Caltech) et al.
We summarize the discussions at a virtual Community Workshop on Cold Atoms in Space concerning the status of cold atom technologies, the prospective scientific and societal opportunities offered by their deployment in space, and the developments needed before cold atoms could be operated in space. The cold atom technologies discussed include atomic clocks, quantum gravimeters and accelerometers, and atom interferometers. [...]

Soliton Merger Rates and Enhanced Axion Dark Matter Decay
/ Du, Xiaolong (Carnegie Inst. Observ. ; UCLA) ; Marsh, David J.E. (King's Coll. London) ; Escudero, Miguel (CERN) ; Benson, Andrew (Carnegie Inst. Observ.) ; Blas, Diego (Barcelona, Autonoma U. ; Barcelona, IFAE) ; Pooni, Charis Kaur (King's Coll. London) ; Fairbairn, Malcolm (King's Coll. London)
Solitons are observed to form in simulations of dark matter (DM) halos consisting of bosonic fields. We use the extended Press-Schechter formalism to compute the mass function of solitons, assuming various forms for the relationship between halo mass and soliton mass. [...]

Cosmology with the Laser Interferometer Space Antenna
/ LISA Cosmology Working Group Collaboration
The Laser Interferometer Space Antenna (LISA) has two scientific objectives of cosmological focus: to probe the expansion rate of the universe, and to understand stochastic gravitational-wave backgrounds and their implications for early universe and particle physics, from the MeV to the Planck scale. However, the range of potential cosmological applications of gravitational wave observations extends well beyond these two objectives. [...]

New horizons for fundamental physics with LISA
/ LISA Collaboration
The Laser Interferometer Space Antenna (LISA) has the potential to reveal wonders about the fundamental theory of nature at play in the extreme gravity regime, where the gravitational interaction is both strong and dynamical. In this white paper, the Fundamental Physics Working Group of the LISA Consortium summarizes the current topics in fundamental physics where LISA observations of GWs can be expected to provide key input.

New Constraints on the Mass of Fermionic Dark Matter from Dwarf Spheroidal Galaxies
/ Alvey, James (King's Coll. London) ; Sabti, Nashwan (King's Coll. London) ; Tiki, Victoria (Leiden U.) ; Blas, Diego (King's Coll. London) ; Bondarenko, Kyrylo (CERN ; Ecole Polytechnique, Lausanne) ; Boyarsky, Alexey (Leiden U.) ; Escudero, Miguel (King's Coll. London ; Munich, Tech. U.) ; Fairbairn, Malcolm (King's Coll. London) ; Orkney, Matthew (Surrey U.) ; Read, Justin I. (Surrey U.)
Dwarf spheroidal galaxies are excellent systems to probe the nature of fermionic dark matter due to their high observed dark matter phase-space density. In this work, we review, revise and improve upon previous phase-space considerations to obtain lower bounds on the mass of fermionic dark matter particles. [...]
