Mapping optically variable quasars towards the galactic plane

J. G. Fernandez-Trincado, T. Verdugo, C. Reylé +13

We present preliminary results of the CIDA Equatorial Variability Survey (CEVS), looking for quasar (hereafter QSO) candidates near the Galactic plane. The CEVS contains photometri…

No Excess of RR Lyrae Stars in the Canis Major Overdensity

Cecilia Mateu, A. Katherina Vivas, Robert Zinn +2

Our multi-epoch survey of ~20 sq. deg. of the Canis Major overdensity has detected only 10 RR Lyrae stars (RRLS). We show that this number is consistent with the number expected fr…

Systematic motions in the Galactic plane found in the Hipparcos Catalogue using Herschel's Method

Carlos Abad, Katherine Vieira

Two motions in the galactic plane have been detected and characterized, based on the determination of a common systematic component in Hipparcos catalogue proper motions. The proce…

New Quasars Detected via Variability in the QUEST1 Survey

A. W. Rengstorf, S. L. Mufson, C. Abad +31

By observing the high galactic latitude equatorial sky in drift scan mode with the QUEST (QUasar Equatorial Survey Team) Phase 1 camera, multi-bandpass photometry on a large strip…

A Large Area CCD Camera for the Schmidt Telescope at the Venezuelan National Astronomical Observatory

C. Baltay, J. A. Snyder, P. Andrews +25

We have designed, constructed and put into operation a large area CCD camera that covers a large fraction of the image plane of the 1 meter Schmidt telescope at Llano del Hato in V…

The QUEST RR Lyrae Survey: Confirmation of the Clump at 50 kpc and Other Over-Densities in the Outer Halo

A. K. Vivas, R. Zinn, P. Andrews +33

We have measured the periods and light curves of 148 RR Lyrae variables from V=13.5 to 19.7 from the first 100 sq. degrees of the QUEST RR Lyrae survey. Approximately 55% of these…
