Hamilton's Object Revisited: A challenging source redshift of a strong lensing configuration
Jenny Wagner, Emilio E. Falco
Low-resolution spectrographs used to have difficulties in determining redshifts of galaxies at and . Spectral emission and absorption lines of magnesium and…
A Study of Gravitational Lens Chromaticity with the Hubble Space Telescope
José A. Muñoz, Evencio Mediavilla, Christopher S. Kochanek +2
We report Hubble Space Telescope observations of 6 gravitational lenses with the Advanced Camera for Surveys. We measured the flux ratios between the lensed images in 6 filters fro…
Constraining the low-mass end of the Initial Mass Function with Gravitational Lensing
Ignacio Ferreras, Prasenjit Saha, Dominik Leier +2
The low-mass end of the stellar Initial Mass Function (IMF) is constrained by focusing on the baryon-dominated central regions of strong lensing galaxies. We study in this letter t…
The Quasar Accretion Disk Size -- Black Hole Mass Relation
Christopher W. Morgan, C. S. Kochanek, Nicholas D . Morgan +1
We use the microlensing variability observed for eleven gravitationally lensed quasars to show that the accretion disk size at a rest-frame wavelength of 2500 Angstroms is related…
The Quasar Accretion Disk Size - Black Hole Mass Relation
Christopher W. Morgan, C. S. Kochanek, Nicholas D. Morgan +1
We use the microlensing variability observed for nine gravitationally lensed quasars to show that the accretion disk size at 2500 Angstroms is related to the black hole mass by log…
The K-Band Galaxy Luminosity Function
C. S. Kochanek, M. A. Pahre, E. E. Falco +6
We measured the K-band luminosity function using a complete sample of 4192 morphologically-typed 2MASS galaxies with 7 < K < 11.25 mag spread over 2.12 str. Early-type (T < -0.5) a…
