Recoiling Black Holes in Merging Galaxies
Laura Blecha, Thomas J. Cox, Abraham Loeb +1
Gravitational-wave (GW) recoil of merging supermassive black holes (SMBHs) may influence the co-evolution of SMBHs and their host galaxies. We examine this possibility using SPH/N-…
The cosmic X-ray and gamma-ray background from dark matter annihilation
Jesus Zavala, Mark Vogelsberger, Tracy R. Slatyer +2
(Abridged) The extragalactic background light (EBL) observed at multiple wavelengths is a promising tool to probe the nature of dark matter since it might contain a significant con…
Cores in Dwarf Galaxies from Dark Matter with a Yukawa Potential
Abraham Loeb, Neal Weiner
We show that cold dark matter particles interacting through a Yukawa potential could naturally explain the recently observed cores in dwarf galaxies without affecting the dynamics…
Probing the Epoch of Reionization with the Lyman Alpha Forest at z~4-5
Renyue Cen, Patrick McDonald, Hy Trac +1
The inhomogeneous cosmological reionization process leaves tangible imprints in the intergalactic medium down to z=4-5. The Lyman-alpha forest flux power spectrum provides a potent…
Imaging an Event Horizon: submm-VLBI of a Super Massive Black Hole
Sheperd Doeleman, Eric Agol, Don Backer +20
A long standing goal in astrophysics is to directly observe the immediate environment of a black hole with angular resolution comparable to the event horizon. Realizing this goal w…
The hyperfine transition of 3He+ as a probe of the intergalactic medium
J. S. Bagla, Abraham Loeb
We explore the prospects of using the hyperfine transition of 3He+ as a probe of the intergalactic medium. The emission signal from ionized regions during reionization is expected…
