SETI via Leakage from Light Sails in Exoplanetary Systems
James Guillochon, Abraham Loeb
The primary challenge of rocket propulsion is the burden of needing to accelerate the spacecraft's own fuel, resulting in only a logarithmic gain in maximum speed as propellant is…
The Infinity Pool
Abraham Loeb
Career opportunities are often a matter of chance, but also of willingness to cross interdisciplinary boundaries.
Measuring the Direction and Angular Velocity of a Black Hole Accretion Disk via Lagged Interferometric Covariance
Michael D. Johnson, Abraham Loeb, Hotaka Shiokawa +2
We show that interferometry can be applied to study irregular, rapidly rotating structures, as are expected in the turbulent accretion flow near a black hole. Specifically, we anal…
Probing the Spacetime Around Supermassive Black Holes with Ejected Plasma Blobs
Pierre Christian, Abraham Loeb
Millimeter-wavelength VLBI observations of the supermassive black holes in Sgr A* and M87 by the Event Horizon Telescope could potentially trace the dynamics of ejected plasma blob…
How to collect matches that will catch fire
Abraham Loeb
How can we select a cohort of promising astrophysicists before they have made their discoveries? This is the fundamental challenge of academic planning. I argue that science can on…
Foregrounds in Wide-Field Redshifted 21 cm Power Spectra
Nithyanandan Thyagarajan, Daniel C. Jacobs, Judd D. Bowman +61
Detection of 21~cm emission of HI from the epoch of reionization, at redshifts z>6, is limited primarily by foreground emission. We investigate the signatures of wide-field measure…
