On the influence of the environment on galactic chemical abundances
L. S. Pilyugin, E. K. Grebel, I. A. Zinchenko +2
We examine the influence of the environment on the chemical abundances of late-type galaxies with masses of 10^9.1 M_sun - 10^11 M_sun using data from the Sloan Digital Sky Survey(…
MiNDSTEp differential photometry of the gravitationally lensed quasars WFI2033-4723 and HE0047-1756: Microlensing and a new time delay
E. Giannini, R. W. Schmidt, J. Wambsganß +52
We present V and R photometry of the gravitationally lensed quasars WFI2033-4723 and HE0047-1756. The data were taken by the MiNDSTEp collaboration with the 1.54 m Danish telescope…
Do Some AGN Lack X-ray Emission?
Charlotte Simmonds, Franz E. Bauer, Trinh X. Thuan +3
Intermediate-Mass Black Holes (IMBHs) are thought to be the seeds of early Supermassive Black Holes (SMBHs). While 100 IMBH and small SMBH candidates have been…
Lyman-alpha spectral properties of five newly discovered Lyman continuum emitters
A. Verhamme, I. Orlitova, D. Schaerer +4
We have recently reported the discovery of five low redshift Lyman continuum (LyC) emitters (LCEs, hereafter) with absolute escape fractions fesc(LyC) ranging from 6 to 13%, higher…
Oxygen abundance maps of CALIFA galaxies
I. A. Zinchenko, L. S. Pilyugin, E. K. Grebel +2
We construct maps of the oxygen abundance distribution across the disks of 88 galaxies using CALIFA data release 2 (DR2) spectra. The position of the center of a galaxy (coordinate…
