HFF-DeepSpace photometric catalogs of the 12 Hubble frontier fields, clusters, and parallels : photometry, photometric redshifts, and stellar masses Universiteit Gent
The CANDELS/SHARDS multiwavelength catalog in GOODS-N : photometry, photometric redshifts, stellar masses, emission-line fluxes, and star formation rates Universiteit Gent
We present a WFC3 F160W (H-band) selected catalog in the CANDELS/GOODS-N field containing photometry from the ultraviolet (UV) to the far-infrared (IR), photometric redshifts, and stellar parameters derived from the analysis of the multiwavelength data. The catalog contains 35,445 sources over the 171 arcmin(2) of the CANDELS F160W mosaic. The 5 sigma detection limits (within an aperture of radius 0 ''.17) of the mosaic range between H = 27.8, ...
Photometric study of selected cataclysmic variables II. Time-series photometry of nine systems. Vrije Universiteit Brussel
We present time-series photometry of nine cataclysmic variables: EI UMa, V844 Her, V751 Cyg, V516 Cyg, GZ Cnc, TY Psc, V1315 Aql, ASAS J002511+1217.2, V1315 Aql and LN UMa. The observations were conducted at various observatories, covering 170 hours and comprising 7,850 data points in total.
For the majority of targets we confirm previously reported periodicities and for some of them we give, for the first time through photometry, their ...

Astronomical Photometric Precision and Differential Photometers Vrije Universiteit Brussel
The purpose of this session is to describe and discuss the development of astronomical photometry to provide increasingly useful tests of astrophysical theories. It will focus on the achievement of precision and accuracy, and span the interval from the photovisual and photographic era to the present CCD age. Both instruments and techniques are to be discussed, and discussion will include photometric systems and transformations, absolute ...
CANDELS multi-wavelength catalogs : source identification and photometry in the CANDELS Extended Groth Strip Universiteit Gent
We present a 0.4-8 mu m multi-wavelength photometric catalog in the Extended Groth Strip (EGS) field. This catalog is built on the Hubble Space Telescope (HST) WFC3 and ACS data from the Cosmic Assembly Nearinfrared Deep Extragalactic Legacy Survey (CANDELS), and it incorporates the existing HST data from the Allwavelength Extended Groth strip International Survey (AEGIS) and the 3D-HST program. The catalog is based on detections in the F160W ...
uvby photometry of theta Tucanae Vrije Universiteit Brussel
theta Tucanae (HR 139, V=6.11, A7 IV) is a binary with a delta Scuti primary that was the subject of several photometric monitoring campaigns during the 1970s and again in the 1990s.
The data presented in this paper were collected during an observing campaign from mid-September to the end of October 1993 at ESO La Silla, Chile, using the simultaneous Stroemgren uvby photometer at the SAT telescope during 25 partial nights.

BRITE-Constellation high-precision time-dependent photometry of the early O-type supergiant zeta Puppis unveils the photospheric drivers of its small- and large-scale wind structures Vrije Universiteit Brussel KU Leuven
From 5.5 months of dual-band optical photometric monitoring at the 1 mmag level, BRITE-Constellation has revealed two simultaneous types of variability in the O4I(n)fp star ζ Puppis: one single periodic non-sinusoidal component superimposed on a stochastic component. The monoperiodic component is the 1.78-d signal previously detected by Coriolis/Solar Mass Ejection Imager, but this time along with a prominent first harmonic. The shape of this ...
