The hardware of the OSIRIS instrument is nearly complete. The instrument commissioning will continue with the validation of the remaining observing modes that...
Outcome of Six Candidate Transiting Planets from a TrES Field in Andromeda
Driven by the incomplete understanding of the formation of gas giant extrasolar planets and of their mass-radius relationship, several ground-based, wide-field...
Outer density profiles of 19 Galactic globular clusters from deep and wide-field imaging
Using deep photometric data from Wide Field Camera at the Isaac Newton Telescope and Wide Field Imager at the ESO 2.2-m telescope we measure the outer number...
Overview of the SDSS-IV MaNGA Survey: Mapping nearby Galaxies at Apache Point Observatory
We present an overview of a new integral field spectroscopic survey called MaNGA (Mapping Nearby Galaxies at Apache Point Observatory), one of three core...
Parsec-scale Dust Emission from the Polar Region in the Type 2 Nucleus of NGC 424
Advancements in infrared (IR) interferometry open up the possibility to spatially resolve active galactic nuclei (AGNs) on the parsec-scale level and study the...
PASS: An All Sky Survey for the Detection of Transiting Extrasolar Planets and for Permanent Variable Star Tracking
An overview is given of the Permanent All Sky Survey (PASS) project. The primary goal of PASS is the detection of all transiting giant planets in the entire sky...
Period, epoch, and prediction errors of ephemerides from continuous sets of timing measurements
Space missions such as Kepler and CoRoT have led to large numbers of eclipse or transit measurements in nearly continuous time series. This paper shows how to...
Phase curve and geometric albedo of WASP-43b measured with CHEOPS, TESS, and HST WFC3/UVIS
Context. Observations of the phase curves and secondary eclipses of extrasolar planets provide a window onto the composition and thermal structure of the...
Phase diversity restoration of sunspot images. I. Relations between penumbral and photospheric features
We investigate the dynamics of and the relations between small-scale penumbral and photospheric features near the outer penumbral boundary: penumbral grains...
