Peering into the Dark (Ages) with Low-Frequency Space Interferometers
Leon Koopmans, Rennan Barkana, Mark Bentum +28
Neutral hydrogen pervades the infant Universe, and its redshifted 21-cm signal allows one to chart the Universe. This signal allows one to probe astrophysical processes such as the…
Compact Objects and Accretion Disks
Roger Blandford, Eric Agol, Avery Broderick +3
Recent developments in the spectropolarimetric study of compact objects, specifically black holes (stellar and massive) and neutron stars are reviewed. The lectures are organized a…
Astro2020 Science White Paper: First Stars and Black Holes at Cosmic Dawn with Redshifted 21-cm Observations
Jordan Mirocha, Daniel Jacobs, Josh Dillon +39
The "cosmic dawn" refers to the period of the Universe's history when stars and black holes first formed and began heating and ionizing hydrogen in the intergalactic medium (IGM).…
Cosmology with the Highly Redshifted 21cm Line
Adrian Liu, James Aguirre, Yacine Ali-Haimoud +47
In addition to being a probe of Cosmic Dawn and Epoch of Reionization astrophysics, the 21cm line at is also a powerful way to constrain cosmology. Its power derives from sev…
Two-dimensional kinematics of SLACS lenses: II. Combined lensing and dynamics analysis of early-type galaxies at z = 0.08 - 0.33
Matteo Barnabe, Oliver Czoske, Leon Koopmans +3
We present the first detailed analysis of the mass and dynamical structure of a sample of six early-type lens galaxies, selected from the Sloan Lens ACS Survey, in the redshift ran…
Discovering the Sky at the Longest Wavelengths with Small Satellite Constellations
Xuelei Chen, Jack Burns, Leon Koopmans +29
Due to ionosphere absorption and the interference by natural and artificial radio emissions, ground observation of the sky at the decameter or longer is very difficult. This unexpl…
