An Analytic Model of the Physical Properties of Galaxy Clusters (2009)

Bulbul, G. Esra, Hasler, Nicole, Bonamente, Massimiliano, Joy, Marshall

We introduce an analytic model of the diffuse intergalactic medium in galaxy clusters based on a polytropic equation of state for the gas in hydrostatic equilibrium with the cluster gravitational...

We present the first measurement of the relationship between the Sunyaev-Zel'dovich effect (SZE) signal and the mass of galaxy clusters that uses gravitational lensing to measure cluster mass, based...

Dark matter and Modified Newtonian Dynamics in a sample of high-redshift galaxy clusters observed with Chandra (2009)

Blaksley, Carl, Bonamente, Massimiliano

We compare the measurement of the gravitational mass of 38 high-redshift galaxy clusters observed by Chandra using Modified Newtonian Dynamics (MOND) and standard Newtonian gravity. Our analysis...

Swift XRT Observations of the Possible Dark Galaxy VIRGOHI 21 (2008)

Bonamente, Massimiliano, Swartz, Douglas, Weisskopf, Martin, Murray, Steven

\swift \xrt observations of the \hi line source \VV were performed on April 22 and April 26, 2008 for a total exposure time of 9.2ks. This is the first pointed X-ray observation of \VV, a putative...

Scaling relations from Sunyaev-Zel'dovich effect and Chandra X-ray measurements of high-redshift galaxy clusters (2008)

The extreme ultraviolet excess emission in five clusters of galaxies revisited (2005)

Durret, Florence, Slezak, Eric, Lieu, Richard, Santos, Sergio Dos, Bonamente, Massimiliano

Evidence for excess extreme ultraviolet (EUV) emission over a tail of X-ray gas bremsstrahlung emission has been building up recently, but in some cases remains controversial, mostly due to the...

Markov Chain Monte Carlo joint analysis of Chandra X-ray imaging spectroscopy and Sunyaev-Zeldovich Effect data (2004)

Bonamente, Massimiliano, Joy, Marshall K., Carlstrom, John E., Reese, Erik D., LaRoque, Samuel J.

X-ray and Sunyaev-Zeldovich Effect data can be combined to determine the distance to galaxy clusters. High-resolution X-ray data are now available from the Chandra Observatory, which provides both...

FUSE Observations of Galactic and Intrinsic Absorption in the Spectrum of the Seyfert 1 Galaxy 2MASX J21362313-6224008 (2003)

Bonamente, Massimiliano, Dixon, W. Van Dyke

We present the far-ultraviolet spectrum of the Seyfert 1 galaxy 2MASX J21362313-6224008 obtained with the Far Ultraviolet Spectroscopic Explorer (FUSE). The spectrum features absorption from Galactic...

EUV and X-ray observation of Abell 2199: a three-phase intracluster medium with a massive warm component (2000)

Lieu, Richard, Bonamente, Massimiliano, Mittaz, Jonathan P. D.

Various independent ways of constraining the Hubble constant and the baryonic content of the universe finally converged at a consensus range of values which indicates that at the present epoch the...

The multi-phase nature of three intracluster media (2000)

Bonamente, Massimiliano, Lieu, Richard

Among the models proposed to account for the new component of diffuse EUV and soft X-ray emission from clusters of galaxies (first discovered in Virgo) are two key contestants: the non-thermal...
