Kavli Affiliate: Herman L. Marshall | First 5 Authors: Juri Poutanen, Sergey S. Tsygankov, Victor Doroshenko, Sofia V. Forsblom, Peter Jenke | Summary: Discovery of pulsations from a number of ULXs proved that accretion onto neutron stars can produce luminosities exceeding the Eddington limit by several orders of magnitude. The conditions necessary to achieve such […]

Kavli Affiliate: Herman L. Marshall | First 5 Authors: Juri Poutanen, Sergey S. Tsygankov, Victor Doroshenko, Sofia V. Forsblom, Peter Jenke | Summary: Discovery of pulsations from a number of ultra-luminous X-ray (ULX) sources proved that accretion onto neutron stars can produce luminosities exceeding the Eddington limit by a couple of orders of magnitude. The […]

Kavli Affiliate: Andrey Kravtsov | First 5 Authors: Zewei Wu, Andrey Kravtsov, , , | Summary: We present estimates of the ultraviolet (UV) and Lyman continuum flux density contributed by galaxies of luminosities from $M_{rm UV}approx -25$ to $M_{rm UV}=-4$ at redshifts $5leq zleq 10$ using a galaxy formation model that reproduces properties of local […]

Kavli Affiliate: Anna Frebel | First 5 Authors: Hillary Diane Andales, Ananda Santos Figueiredo, Casey Gordon Fienberg, Mohammad K. Mardini, Anna Frebel | Summary: We present a detailed chemical abundance and kinematic analysis of six extremely metal-poor ($-4.2 leq$ [Fe/H] $leq-$2.9) halo stars with very low neutron-capture abundances ([Sr/H] and [Ba/H]) based on high-resolution Magellan/MIKE […]
Kavli Affiliate: Ke Wang | First 5 Authors: Ke Wang, Nikolaos Dimitriadis, Guillermo Ortiz-Jimenez, François Fleuret, Pascal Frossard | Summary: Model merging and task arithmetic have emerged as promising scalable approaches to merge multiple single-task checkpoints to one multi-task model, but their applicability is reduced by significant performance loss. Previous works have linked these drops […]
Kavli Affiliate: Erin Kara | First 5 Authors: Ole König, Guglielmo Mastroserio, Thomas Dauser, Mariano Méndez, Jingyi Wang | Summary: The Neutron Star Interior Composition Explorer (NICER) monitoring campaign of Cyg X-1 allows us to study its spectral-timing behavior at energies ${<}1$ keV across all states. The hard state power spectrum can be decomposed into […]
