Black Hole masses for 14 gravitational lensed quasars
A. Melo, V. Motta, J. Mejía-Restrepo +7
We estimate black hole masses (M) for 14 gravitationally lensed quasars using the Balmer lines along with estimates based on MgII and CIV emission lines for four and two…
The Longest Delay: a 14.5 Yr Campaign to Determine the Third Time Delay in the Lensing Cluster SDSS~J1004+4112
J. A. Muñoz, C. S. Kochanek, J. Fohlmeister +3
We present new light curves for the four bright images of the five image cluster-lensed quasar gravitational lens system SDSS~J1004+4112. The light curves span 14.5 yr and allow me…
First black hole mass estimation for the quadruple lensed system WGD2038-4008
A. Melo, V. Motta, N. Godoy +6
The quadruple lensed system WGD2038-4008 was recently discovered with the help of new techniques and observations. Even though black hole mass has been estimated for lensed quasars…
Dissecting the strong lensing galaxy cluster MS 04400204 II. New optical spectroscopic observations in a wider area and cluster dynamical state
E. R. Carrasco, T. Verdugo, V. Motta +5
We present an optical study of the strong lensing galaxy cluster MS 0440.50204 at , based on CFHT/MegaCam g', r'-photometry and GMOS/Gemini and CFHT/MOS/SIS spectrosc…
Individual Estimates of the Virial Factor in 10 Quasars: Implications on the Kinematics of the Broad Line Region
E. Mediavilla, J. Jiménez-Vicente, J. Mejí A-Restrepo +5
Assuming a gravitational origin for the Fe III2039-2113 redshift and using microlensing based estimates of the size of the region emitting this feature, we obtain individual me…
Microlensing Analysis for the gravitational lens systems SDSS0924+0219, Q1355-2257, and SDSS1029+2623
K. Rojas, V. Motta, E. Mediavilla +3
We use spectroscopic observations of the gravitationally lensed systems SDSS0924+0219(BC), Q1355-2257(AB), and SDSS1029+2623(BC) to analyze microlensing and dust extinction in the…
