Towards A Universal Analytical Model of Population III Star Formation: A Bridge Between Cosmological Scales and Protostars
James Gurian, Boyuan Liu, Donghui Jeong +4
We construct an analytical model of Population III star formation that connects the cosmological radiation background to sub-AU protostellar disk fragmentation, a dynamic range ina…

Determining the Hubble Constant through Cross-Correlation of Galaxies and Gravitational Waves
Jiaming Pan, Dragan Huterer, Camille Avestruz +4
Gravitational wave (GW) standard sirens have the potential to measure the Hubble constant in the local universe independently of the distance ladder, and thus offer unique ne…

An Analytic Model of Gravitational Collapse Induced by Radiative Cooling: Instability Scale, Infall Velocity, and Accretion Rate
James Gurian, Boyuan Liu, Donghui Jeong +3
We present an analytic description of the spherically symmetric gravitational collapse of radiatively cooling gas clouds, which illustrates the mechanism by which radiative cooling…
