Halo Luminosity Function From Photometric Calibration of the Revised NLTT
Andrew Gould, Juna A. Kollmeier, Julio Chaname +1
We calibrate the photographic photometry of the revised New Luyten Two-Tenths catalog (rNLTT) by matching 3448 rNLTT stars to the Sloan Digital Sky Survey (SDSS). The correction is…
A Mass Measurement for the Missing Baryons in the Warm-Hot Intergalactic Medium via the X-ray Forest
F. Nicastro, S. Mathur, M. Elvis +7
Recent Cosmological measurements indicate that baryons comprise about four percent of the total mass-energy density of the Universe, which is in accord with the predictions arising…
Rotation Velocities of Two Low Luminosity Field Galaxies
James Pizagno, Michael R. Blanton, David H. Weinberg +2
We present H-alpha rotation curves of two low luminosity field galaxies with r-band absolute magnitudes M_r=-13.9^{+0.8}_{-0.5} and M_r=-14.7^{+0.3}_{-0.2} (for h=0.7; the large er…
A High Temperature Liquid Plasma Model of the Sun
Pierre-Marie Robitaille
In this work, a liquid model of the Sun is presented wherein the entire solar mass is viewed as a high density/high energy plasma. This model challenges our current understanding o…
Black-Hole Mass Measurements
M. Vestergaard
The applicability and apparent uncertainties of the techniques currently available for measuring or estimating black-hole masses in AGNs are briefly summarized.
Evidence for Early or Efficient Black-Hole Growth
M. Vestergaard
Mass estimates, based on scaling relationships, are presented of central black holes in luminous quasars at a range of redshifts (z < 0.5, 1.2 ~< z ~< 6.3). The data show that very…
