Imaging an Event Horizon: submm-VLBI of a Super Massive Black Hole (2009)
Doeleman, Sheperd, Agol, Eric, Backer, Don, Baganoff, Fred, Bower, Geoffrey C., Broderick, Avery, ...
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 would open a new...
Cooke, Jeff, Cooray, Asantha, Chary, Ranga-Ram, Bromm, Volker, Cen, Renyue, Ellis, Richard, ...
The cosmic dark ages are the mysterious epoch during which the pristine gas began to condense and ultimately form the first stars. Although these beginnings have long been a topic of theoretical...
The Dynamic X-ray Sky of the Local Universe (2009)
Soderberg, Alicia M., Grindlay, Jonathan E., Bloom, Joshua S., Gezari, Suvi, Piro, Anthony L., Belloni, Tomaso, ...
Over the next decade, we can expect time domain astronomy to flourish at optical and radio wavelengths. In parallel with these efforts, a dedicated transient "machine" operating at higher energies...
21 cm Intensity Mapping (2009)
Peterson, Jeffrey B., Aleksan, Roy, Ansari, Reza, Bandura, Kevin, Bond, Dick, Bunton, John, ...
Using the 21 cm line, observed all-sky and across the redshift range from 0 to 5, the large scale structure of the Universe can be mapped in three dimensions. This can be accomplished by studying...
Cooray, Asantha, Amblard, Alexandre, Beichman, Charles, Benford, Dominic, Bernstein, Rebecca, Bock, James, ...
(Brief Summary) What is the total radiative content of the Universe since the epoch of recombination? The extragalactic background light (EBL) spectrum captures the redshifted energy released from...
Signatures of the First Stars in the Universe (2007)
. We calculate the observable signatures of the first generation of stars at high redshifts (5 ! z ! 10 3 ). We determine the cosmic star--formation history, using an extension of the...
The Imprint of Cosmic Reionization on Galaxy Clustering (2007)
We consider the effect of reionization on the clustering properties of galaxy samples at intermediate redshifts (z~0.3-5.5). Current models for the reionization of intergalactic hydrogen predict that...
The Correlation Between Star Formation and 21cm Emission During the Reionization Epoch (2007)
Wyithe, Stuart, Loeb, Avi, Schmidt, Brian
Reionization is thought to be dominated by low mass galaxies, while direct observations of resolved galaxies probe only the most massive, rarest objects. The cross-correlation between fluctuations in...
The correlation between the distribution of galaxies and 21cm emission at high redshifts (2006)
Deep surveys have recently discovered galaxies at the tail end of the epoch of reionization. In the near future, these discoveries will be complemented by a new generation of low-frequency radio...
Probing the Spacetime Around Sgr A* with Radio Pulsars (2003)
The supermassive black hole at the Galactic center harbors a bound cluster of massive stars that should leave neutron-star remnants. Extrapolating from the available data, we estimate that 100-1000...

Empirical Constraints on the First Stars and Quasars (1998)
Empirical studies of the first generation of stars and quasars in the Universe will likely become feasible over the next decade. The Next Generation Space Telescope will provide direct imaging and...
