Reducing low signal-to-noise FUSE spectra: confirmation of Lyman continuum escape from Haro 11
E. Leitet, N. Bergvall, N. Piskunov +1
Galaxies are believed to be the main providers of Lyman continuum (LyC) photons during the early phases of the cosmic reionization. Little is known however, when it comes to escape…
Variability and stability in blazar jets on time scales of years: Optical polarization monitoring of OJ287 in 2005-2009
C. Villforth, K. Nilsson, J. Heidt +45
(Abridged) OJ287 is a BL Lac object that has shown double-peaked bursts at regular intervals of ~12 yr during the last ~40 yr. We analyse optical photopolarimetric monitoring data…
The temporal and spatial evolution of the starburst in ESO 338-IG04 as probed by its star clusters
G. Ostlin, E. Zackrisson, N. Bergvall +1
In this paper we use ultra-violet (UV) and optical HST photometry in five bands, and an extensive set of spectral evolutionary synthesis scenarios to investigate the age and masses…
Constraining Dark Matter with the Long-Term Variability of Quasars
E. Zackrisson, N. Bergvall, P. Helbig
By comparing the results of numerical microlensing simulations to the observed long-term variability of quasars, strong upper limits on the cosmological density of compact objects…
