Galaxy flows within 8,000 km/s from Numerical Action methods

Autor: Shaya, Edward, Tully, R. Brent, Pomarède, Daniel, Peel, Alan

The trajectories since z=4 of systems of galaxies (`halos') with cz < 8,000 km/s are found through Numerical Action reconstructions. A set of 9,719 halos from a 2MASS group catalog and Cosmicflows-3 catalogs are given attention. Present distances are

Our Peculiar Motion Away from the Local Void

Autor: Tully, R. Brent, Shaya, Edward J., Karachentsev, Igor D., Courtois, Helene M., Kocevski, Dale D., Rizzi, Luca, Peel, Alan

Publikováno v: Astrophys.J.676:184-205,2008

The peculiar velocity of the Local Group of galaxies manifested in the Cosmic Microwave Background dipole is found to decompose into three dominant components. The three components are clearly separated because they arise on distinct spatial scales a

Mass Selection Bias in Galaxy Cluster Peculiar Velocities from the Kinetic Sunyaev-Zel'dovich Effect

Autor: Peel, Alan C.

Publikováno v: Mon.Not.Roy.Astron.Soc. 365 (2006) 1191-1202

Upcoming surveys for galaxy clusters using the Sunyaev-Zel'dovich effect are potentially sensitive enough to create a peculiar velocity catalog. The statistics of these peculiar velocities are sensitive to cosmological parameters. We develop a method

COMPASS: An Upper Limit on CMB Polarization at an Angular Scale of 20 arc minutes

Autor: Farese, Philip C., Dall'Oglio, Giorgio, Gundersen, Joshua O., Keating, Brian G., Klawikowski, Slade, Knox, Lloyd, Levy, Alan, Lubin, Philip M., O'Dell, Chris W., Peel, Alan, Piccirillo, Lucio, Ruhl, John, Timbie, Peter T.

Publikováno v: Astrophys.J.610:625-634,2004

COMPASS is an on-axis 2.6 meter telescope coupled to a correlation polarimeter operating at a wavelength of 1 cm. The entire instrument was built specifically for CMB polarization studies. We report here on observations of February 2001 - April 2001

COMPASS: An Instrument for Measuring the Polarization of the CMB on Intermediate Angular Scales

Autor: Farese, Philip C., Dall'Oglio, Giorgio, Gundersen, Josh, Keating, Brian, Klawikowski, Slade, Knox, Lloyd, Levy, Alan, O'Dell, Chris, Peel, Alan, Piccirillo, Lucio, Ruhl, John, Timbie, Peter

COMPASS is an on-axis 2.6 meter telescope coupled to a correlation polarimeter. The entire instrument was built specifically for CMB polarization studies. Careful attention was given to receiver and optics design, stability of the pointing platform,

Gravitational Potential Reconstruction from Peculiar Velocity and Weak Lensing Measurements

Autor: Doré, Olivier, Knox, Lloyd, Peel, Alan

Publikováno v: Astrophys.J. 585 (2003) L81-L84

We present an analytic method for rapidly forecasting the accuracy of gravitational potential reconstruction possible from measurement of radial peculiar velocities of every galaxy cluster with M > M_th in solid angle \theta^2 and over redshift range
