An Improved Cluster Richness Estimator

Eduardo Rozo, Eli S. Rykoff, Benjamin P. Koester +11

Minimizing the scatter between cluster mass and accessible observables is an important goal for cluster cosmology. In this work, we introduce a new matched filter richness estimato…

Fuel for Galaxy Disks

M. E. Putman, J. Grcevich, J. E. G. Peek

Halo clouds have been found about the three largest galaxies of the Local Group and in the halos of nearby spirals. This suggests they are a relatively generic feature of the galax…

The high energy emission from black holes

M. D. Caballero-Garcia, J. M. Miller, E. Kuulkers

The origin of the high energy emission (X-rays and gamma-rays) from black holes is still a matter of debate. We present new evidence that hard X-ray emission in the low/hard state…

Massive stars: Feedback effects in the local universe

M. S. Oey, C. J. Clarke

We examine self-consistent parameterizations of the high-mass stellar population and resulting feedback, including mechanical, radiative, and chemical feedback, as we understand th…

High-Velocity Clouds in M 83 and M 51

Eric D. Miller, Joel N. Bregman

Various scenarios have been proposed to explain the origin of the Galactic high-velocity clouds, predicting different distances and implying widely varying properties for the Galax…

BL Lacertae: the multiwavelength campaign of 2000

M. Ravasio, G. Tagliaferri, G. Ghisellini +9

We present two BeppoSAX observations of BL Lacertae as part of a multiwavelength radio-to-TeV campaign. During the first observation we observe a faint Compton spectrum, while duri…
