Gravitational Test Beyond the First Post-Newtonian Order with the Shadow of the M87 Black Hole
Dimitrios Psaltis, Lia Medeiros, Pierre Christian +185
The 2017 Event Horizon Telescope (EHT) observations of the central source in M87 have led to the first measurement of the size of a black-hole shadow. This observation offers a new…
Biases and Cosmic Variance in Molecular Gas Abundance Measurements
Ryan P. Keenan, Daniel P. Marrone, Garrett K. Keating
Recent deep millimeter-wave surveys attempt to measure the carbon monoxide (CO) luminosity function and mean molecular gas density through blind detections of CO emission lines. Wh…
The Terahertz Intensity Mapper (TIM): a Next-Generation Experiment for Galaxy Evolution Studies
Joaquin Vieira, James Aguirre, C. Matt Bradford +22
Understanding the formation and evolution of galaxies over cosmic time is one of the foremost goals of astrophysics and cosmology today. The cosmic star formation rate has undergon…
Monitoring the Morphology of M87* in 2009-2017 with the Event Horizon Telescope
Maciek Wielgus, Kazunori Akiyama, Lindy Blackburn +26
The Event Horizon Telescope (EHT) has recently delivered the first resolved images of M87*, the supermassive black hole in the center of the M87 galaxy. These images were produced…
An Intensity Mapping Detection of Aggregate CO Line Emission at 3 mm
Garrett K. Keating, Daniel P. Marrone, Geoffrey C. Bower +1
We present a detection of molecular gas emission at using the technique of line intensity mapping. We make use of a pair of 3 mm interferometric data sets, the first fro…
A Prospective ISRO-CfA Himalayan Sub-millimeter-wave Observatory Initiative
T. K. Sridharan, Shmuel Bialy, Raymond Blundell +20
The Smithsonian Astrophysical Observatory (SAO), a member of the Center for Astrophysics | Harvard and Smithsonian, is in discussions with the Space Applications Centre (SAC) of th…
