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 UV-Excess Survey of the Northern Galactic Plane (UVEX)

Paul J. Groot, K. Verbeek, R. Greimel +41

The UV-Excess Survey of the Northern Galactic Plane images a 10x185 degree wide band, centered on the Galactic Equator using the 2.5m Isaac Newton Telescope in four bands (U,g,r,He…

SDSS unveils a population of intrinsically faint cataclysmic variables at the minimum orbital period

B. T. Gaensicke, M. Dillon, J. Southworth +15

We discuss the properties of 137 cataclysmic variables (CVs) which are included in the Sloan Digital Sky Survey (SDSS) spectroscopic data base, and for which accurate orbital perio…

The IPHAS-POSS-I proper motion survey of the Galactic Plane

N. R. Deacon, P. J. Groot, J. E. Drew +6

We present a proper motion survey of the Galactic plane, using IPHAS data and POSS-I Schmidt plate data as a first epoch, that probes down to proper motions below 50 milliarcsecond…

Generalised DBI-Quintessence

Burin Gumjudpai, John Ward

We investigate the phase space of a quintessence theory governed by a generalised version of the DBI action, using a combination of numeric and analytic methods. The additional deg…
