We present the first measurement of the relationship between the Sunyaev-Zel'dovich effect signal and the mass of galaxy clusters that uses gravitational lensing to measure cluster mass, based on 14...
Mroczkowski, Tony, Bonamente, Max, Carlstrom, John E., Culverhouse, Thomas L., Greer, Christopher, Hawkins, David, ...
We investigate the utility of a new, self-similar pressure profile for fitting Sunyaev–Zel’dovich (SZ) effect observations of galaxy clusters. Current SZ imaging instruments–such as the...
Sharp, Matthew K., Marrone, Daniel P., Carlstrom, John E., Culverhouse, Thomas, Greer, Christopher, Hawkins, David, ...
We present 30 GHz measurements of the angular power spectrum of the cosmic microwave background (CMB) obtained with the Sunyaev-Zel'dovich Array (SZA). The measurements are sensitive to arcminute...
Event-horizon-scale structure in the supermassive black hole candidate at the Galactic Centre (2008)
Doeleman, Sheperd, Weintroub, Jonathan, Rogers, Alan E. E., Plambeck, Richard, Freund, Robert, Tilanus, Remo P. J., ...
The cores of most galaxies are thought to harbour supermassive black holes, which power galactic nuclei by converting the gravitational energy of accreting matter into radiation (ref 1). Sagittarius...
The Submillimeter Array Polarimeter (2008)
Marrone, Daniel P., Rao, Ramprasad
We describe the Submillimeter Array (SMA) Polarimeter, a polarization converter and feed multiplexer installed on the SMA. The polarimeter uses narrow-band quarter-wave plates to generate circular...
Bonamente, Massimiliano, Marshall, Joy, LaRoque, Samuel J., Carlstrom, John E., Nagai, Daisuke, Marrone, Daniel P.
We present Sunyaev-Zel'dovich Effect (SZE) scaling relations for 38 massive galaxy clusters at redshifts 0.14 ≤ z≤ 0.89, observed with both the Chandra X-ray Observatory and the centimeter-wave...
Infall and Outflow of Molecular Gas in Sgr B2 (2008)
Qin, Sheng-Li, Zhao, Jun-Hui, Moran, James M., Marrone, Daniel P., Patel, Nimesh A., Wang, Jun-Jie, ...
Observations of two H$_2$CO ($3_{03}-2_{02}$ and $3_{21}-2_{20}$) lines and continuum emission at 1.3 mm towards Sgr B2(N) and Sgr B2(M) have been carried out with the SMA. The mosaic maps of Sgr...
Magnetic Fields in the Formation of Sun-Like Stars (2006)
Girart, Josep M., Rao, Ramprasad, Marrone, Daniel P.
We report high-angular-resolution measurements of polarized dust emission toward the low-mass protostellar system NGC 1333 IRAS 4A. We show that in this system the observed magnetic field morphology...

The Submillimeter Polarization of Sgr A* (2006)
Marrone, Daniel P., Moran, James M., Zhao, Jun-Hui, Rao, Ramprasad
We report on the submillimeter properties of Sagittarius A* derived from observations with the Submillimeter Array and its polarimeter. We find that the spectrum of Sgr A* between 230 and 690 GHz is...
