The Square Kilometre Array (SKA) is intended as the next-generation radio telescope and will address fundamental questions in astrophysics, physics, and astrobiology. The international science...

Digital Instrumentation for the Radio Astronomy Community (2009)

Parsons, Aaron, Werthimer, Dan, Backer, Donald, Bastian, Tim, Bower, Geoffrey, Brisken, Walter, ...

Time-to-science is an important figure of merit for digital instrumentation serving the astronomical community. A digital signal processing (DSP) community is forming that uses shared hardware...

The Billion Galaxy Cosmological HI Large Deep Survey (2009)

Myers, Steven T., Abdalla, Filipe B., Blake, Chris, Koopmans, Leon, Lazio, Joseph, Rawlings, Steve

We outline the case for a comprehensive wide and deep survey ultimately targeted at obtaining 21-cm HI line emission spectroscopic observations of more than a billion galaxies to redshift z=1.5 and...

Cosmology from the Highly-Redshifted 21 cm Line (2009)

Furlanetto, Steven, Lidz, Adam, Loeb, Abraham, McQuinn, Matthew, Pritchard, Jonathan, Shapiro, Paul, ...

One of the next decade's most exciting prospects is to explore the cosmic "dark ages," during which the first stars in the Universe formed, with the 21 cm line of neutral hydrogen. At z>6, this light...

Astrophysics from the Highly-Redshifted 21 cm Line (2009)

Furlanetto, Steven, Lidz, Adam, Loeb, Abraham, McQuinn, Matthew, Pritchard, Jonathan, Aguirre, James, ...

The cosmic dark ages and the epoch of reionization, during which the first generations of stars and galaxies formed, are among the most compelling frontiers of extragalactic astrophysics and...

The 'billion galaxy' cosmological HI Large Deep Survey (BiG-CHILDS) (2009)

Myers, Steven T., Abdalla, Filipe B., Blake, Chris, Koopmans, Leon, Lazio, Joseph, Rawlings, Steve

We outline the case for a comprehensive wide and deep survey ultimately targeted at obtaining 21-cm HI line emission spectroscopic observations of more than a billion galaxies to redshift z > 1.5...

An eccentric binary millisecond pulsar in the galactic plane (2008)

Champion, David J., Ransom, Scott M., Lazarus, Patrick, Camilo, Fernando, Bassa, Cees, Kaspi, Victoria M., ...

Binary pulsar systems are superb probes of stellar and binary evolution and the physics of extreme environments. In a survey with the Arecibo telescope, we have found PSR J1903+0327, a radio pulsar...

The discovery of an eccentric millisecond pulsar in the galactic plane (2008)

Champion, David J., Ransom, Scott M., Lazarus, Patrick, Camilo, Fernando, Kaspi, Victoria M., Nice, David J., ...

The evolution of binary systems is governed by their orbital properties and the stellar density of the local environment. Studies of neutron stars in binary star systems offer unique insights into...

On the Enhanced Interstellar Scattering Toward B1849+005 (2004)

Lazio, Joseph

(Abridged) This paper reports new Very Large Array (VLA) and Very Long Baseline Array (VLBA) observations of the extragalactic source B1849+005 at frequencies between 0.33 and 15 GHz and the...

The Radiometric Bode's Law and Extrasolar Planets (2004)

Lazio, Joseph, Farrell, W. M., Dietrick, Jill, Greenlees, Elizabeth, Hogan, Emily, Jones, Christopher, ...

We predict the radio flux densities of the extrasolar planets in the current census, making use of an empirical relation--the radiometric Bode's Law--determined from the five ``magnetic'' planets in...

Mid- and Far-Infrared ISO Limits on Dust Disks around Millisecond Pulsars (2004)

Lazio, Joseph, Fischer, J.

We report 60 and 90 micron observations of 7 millisecond pulsars with ISO. The pulsar PSR B1257+12 is orbited by three planets, and other millisecond pulsars may be orbited by dust disks that...

SKA Hybrids Involving the US LNSD COncept (1998)

Lazio, Joseph

The likely Key Projects for the SKA demand both a large frequency range (potentially 0.06-24 GHz) and a large range of fields of view (potentially less than 1 deg(2) at higher frequencies to as much...
