Incompatibility of Rotation Curves with Gravitational Lensing for TeVeS
Ignacio Ferreras, Nick E. Mavromatos, Mairi Sakellariadou +1
We constrain the one-parameter class of TeVeS models by testing the theory against both rotation curve and strong gravitational lensing data on galactic scales, remaining fully rel…
Could the Galactic disk heating be due to Globular Cluster impacts?
D. Vande Putte, Mark Cropper, Ignacio Ferreras
So far, six mechanisms have been proposed to account for the Galactic disk heating. Of these, the most important appear to be a combination of scattering of stars by molecular clou…
Radio continuum observations of the candidate supermassive black hole in the dwarf elliptical VCC128
Pieter Buyle, Sven De Rijcke, Victor P. Debattista +4
The presence of black holes (BHs) at the centers of dwarf elliptical galaxies (dEs) has been argued both theoretically and observationally. Using archival HST/WFPC2 data, we found…
Predicting spectral features in galaxy spectra from broad-band photometry
F. B. Abdalla, A. Mateus, W. A. Santos +3
We explore the prospects of predicting emission line features present in galaxy spectra given broad-band photometry alone. There is a general consent that colours, and spectral fea…
Towards a Solution for the Ca II Triplet Puzzle : Results from Dwarf Elliptical Galaxies
Dolf Michielsen, Mina Koleva, Philippe Prugniel +6
We present new estimates of ages and metallicities, based on FORS/VLT optical (4400-5500A) spectroscopy, of 16 dwarf elliptical galaxies (dE's) in the Fornax Cluster and in Souther…
Unveiling dark halos in lensing galaxies
Ignacio Ferreras, Prasenjit Saha, Scott Burles
We present a spatially resolved comparison of the stellar-mass and total-mass surface distributions of nine early-type galaxies. The galaxies are a subset of the Sloan Lens ACS sur…
