Kavli Affiliate: John Silverman | Summary:Recent JWST observations have revealed a population of red, compact, high-redshift objects called Little Red Dots (LRDs), whose host components have remained largely unconstrained, possibly due to their extreme compactness. Current morphological studies suggest the presence of extended emission in LRDs at rest-frame ultraviolet wavelengths. However, in the rest-frame optical […]
Kavli Affiliate: Peter Graham | Summary:A terrestrial population of millicharged particles that interact significantly with normal matter can arise if they make up a dark matter subcomponent or if they are light enough to be produced in cosmic ray air showers. Such particles thermalize to terrestrial temperatures through repeated scatters with normal matter in Earth’s […]
Kavli Affiliate: John Silverman | Summary:Recent JWST observations have revealed a population of red, compact, high-redshift objects called ‘Little Red Dots'(LRD), whose host components have remained largely unconstrained, possibly due to their extreme compactness. Current morphological studies have been limited by small samples, as well as by insufficient imaging depth, which may not allow reliable […]

Graham | First 5 Authors: Asher Berlin, Asher Berlin, , , | Summary: A terrestrial population of millicharged particles that interact significantly with normal matter can arise if they make up a dark matter subcomponent or if they are light enough to be produced in cosmic ray air showers. Such particles […]
Kavli Affiliate: Martin Haehnelt | Summary:The fraction of "dark pixels" in the Ly$α$ and other Lyman-series forests at $zsim 5-6$ provides a powerful constraint on the end of the reionization process. Any spectral region showing transmission must be highly ionized, while dark regions could be ionized or neutral, thus the dark pixel fraction provides a […]
Kavli Affiliate: Peter Graham | Summary:A terrestrial population of room-temperature millicharged particles can arise if they make up a dark matter subcomponent or if they are light enough to be produced in cosmic ray air showers. In a companion paper, we showed that a simple electrified shell acts as an efficient accumulator for such particles, […]

Kavli Affiliate: Brad Ramshaw | Summary:Cuprates are the paradigmatic `unconventional’ superconductors: their critical temperature is much higher than can be expected from phonon-mediated pairing; the superconducting gap has $d$-wave symmetry; and the normal-metallic state appears to be far from a conventional Fermi liquid. These and numerous other experimental facts have led to a consensus that […]
Kavli Affiliate: Brad Ramshaw | Summary:We summarize key experimental studies of the low energy properties of overdoped cuprate high temperature superconductors and conclude that a theoretical understanding of the “essential physics" is achievable in terms of a conventional Fermi-liquid treatment of the normal state, and a BCS mean-field treatment of the (d-wave) superconducting state. For […]
