First constraints on Fuzzy Dark Matter from the dynamics of stellar streams in the Milky Way
Nicola C. Amorisco, A. Loeb
We present a novel method to constrain the mass of ultra-light bosons as the dark matter using stellar streams formed by disrupting Globular Clusters in the Milky Way. The turbulen…
Where do ideas come from?
Abraham Loeb
Ideas are nurtured by informal dialogues in environments where mistakes are tolerated and critical thinking is encouraged.
Plasma Constraints on the Cosmological Abundance of Magnetic Monopoles and the Origin of Cosmic Magnetic Fields
Mikhail V. Medvedev, Abraham Loeb
Existing theoretical and observational constraints on the abundance of magnetic monopoles are limited. Here we demonstrate that an ensemble of monopoles forms a plasma whose proper…
Ultra-diffuse galaxies: the high-spin tail of the abundant dwarf galaxy population
N. C. Amorisco, A. Loeb
Recent observations have revealed the existence of an abundant population of faint, low surface brightness (SB) galaxies, which appear to be numerous and ubiquitous in nearby galax…
High-n Hydrogen Recombination Lines from the First Galaxies
Evan Rule, Abraham Loeb, Vladimir Strelnitski
We investigate the prospects of blind and targeted searches in the radio domain (10 MHz to 1 THz) for high-n hydrogen recombination lines from the first generation of galaxies, at…
Escape Fraction of Ionizing Radiation from Starburst Galaxies at High Redshifts
A. Ferrara, A. Loeb
Recent data indicates that the cosmic UV emissivity decreased with decreasing redshift z near the end of reionization. Lacking evidence for very massive early stars, this could sig…
