Abstract We propose a new theory of dark matter based on axion physics and cosmological phase transitions. We show that theories in which a gauge coupling increases through a first-order phase transition naturally result in ‘axion relic pockets’:

Abstract Ultralight dark matter (ULDM) particles of mass m ϕ ≲ 1 eV can form boson stars in DM halos. Collapse of boson stars leads to explosive bosenova emission of copious relativistic ULDM particles. In this work, we analyze the sensitivity of

Abstract Inelastic dark matter with moderate splittings, O $$ \mathcal{O} $$ (few to 150) keV, can upscatter to an excited state in the Earth, with the excited state subsequently decaying, leaving a distinctive monoenergetic photon signal in large un

Background: Directing COVID-19 diagnostic testing to healthcare workers (HCWs) who are likely to be infected has potential to reduce staffing shortages and decrease opportunity for in-hospital transmission; however, HCWs with COVID-19 may exhibit a r

Abstract Background A pleural fluid adenosine deaminase (ADA) has been used globally to assist in the diagnosis of a tuberculous pleural effusion (TPE) with a notable negative predictive value. Case presentation We report a case of a patient with a n

Emission of relativistic axions from transient sources, such as axion star explosions, can lead to observable signatures. We show that axion bursts from collapsing axion stars can be detectable over the wide range of axion masses 10−15eV≲m≲10

Abstract We discuss the sensitivity of the present and near-future axion dark matter experiments to a halo of axions or axion-like particles gravitationally bound to the Earth or the Sun. Such halos, assuming they are formed, can be searched for in a

Abstract We study luminous dark matter signals in models with inelastic scattering. Dark matter χ 1 that scatters inelastically off elements in the Earth is kicked into an excited state χ 2 that can subsequently decay into a monoenergetic photon in

Abstract Axion particles can form macroscopic condensates, whose size can be galactic in scale for models with very small axion masses m ∼ 10−22 eV, and which are sometimes referred to under the name of Fuzzy Dark Matter. Many analyses of these c

Abstract In a previous work, we analyzed collapsing axion stars using the low-energy instanton potential, showing that the total energy is always bounded and that collapsing axion stars do not form black holes. In this paper, we provide a proof that
