Abstract:

The production rate and kinematics of photons produced in association with Z bosons are studied using 2fb-1 of pp虅 collision data collected at the Collider Detector at Fermilab. The cross section for pp虅鈫"+-纬+X (where the leptons " are either muons or electrons with dilepton mass M>40GeV/c2, and where the photon has transverse energy ET纬>7GeV and is well separated from the leptons) is 4.6卤0.2(stat)卤0.3(syst)卤0.3(lum)pb, which is consistent with standard model expectations. We use the photon ET distribution from Z纬 events where the Z has decayed to 渭+渭 -, e+e-, or 谓谓虅 to set limits on anomalous (non standard model) trilinear couplings between photons and Z bosons. 漏 2010 The American Physical Society.

Measuring the low mass end of the M鈥 - 蟽 relation

Abstract:

We show that high quality laser guide star (LGS) adaptive optics (AO) observations of nearby early-type galaxies are possible when the tip-tilt correction is done by guiding on nuclei while the focus compensation due to the changing distance to the sodium layer is made 'open loop'. We achieve corrections such that 40% of flux comes from R<0.2 arcsec. To measure a black hole mass (M鈥) one needs integral field observations of both high spatial resolution and large field of view. With these data it is possible to determine the lower limit to M鈥 even if the spatial resolution of the observations are up to a few times larger than the sphere of influence of the black hole. 漏 2010 American Institute of Physics.

Abstract:

We investigate the accuracy of mass determinations MBH of supermassive black holes in galaxies using dynamical models of the stellar kinematics. We compare 10 of our MBH measurements, using integral-field OASIS kinematics, to published values. For a sample of 25 galaxies we confront our new MBH derived using two modeling methods on the same OASIS data. 漏 2010 American Institute of Physics.
