LoTSS compact groups of galaxies
We use the LOFAR Two-metre Sky Survey (LoTSS) Data Release I to identify the groups of galaxies (and individual galaxies) from the Hickson compact groups (HCG) and... -
B2 0258+35 polarisation images
The contribution of active galactic nuclei to the magnetisation of the Universe can be constrained by knowing their duty cycles, jet and magnetic field morphologies, and the... -
Solar Twins age-chromospheric activity
It is well known that the magnetic activity of solar-type stars decreases with age, but it is widely debated in the literature whether there is a smooth decline or if there is... -
CARMENES SB2 orbital parameters
The CARMENES spectrograph is surveying ~300 M dwarf stars in search for exoplanets. Among the target stars, spectroscopic binary systems have been discovered, which can be used... -
Gaia GraL. II. Known multiply imaged quasars
Thanks to its spatial resolution the ESA/Gaia space mission offers a unique opportunity to discover new multiply-imaged quasars and to study the already known lensed systems at... -
Predicted microlensing events from Gaia DR2
I search for source-lens pairs in Gaia Data Release 2 (GDR2, Cat. I/345) that could potentially lead to microlensing events between 25th July 2014 and 25th July 2026. I estimate... -
M101 radio polarization & magnetic structure
We observed total and polarized radio continuum emission from the spiral galaxy M 101 at {lambda}{lambda}6.2cm and 11.1cm with the Effelsberg telescope. The angular resolutions... -
M31 polarization & magnetic structure
The Andromeda Galaxy (M31) is the nearest grand-design spiral galaxy. Thus far, most studies in the radio regime concentrated on the 10kpc ring. The central region of M31 has... -
Mapping accretion variability in NGC 2264
Our study aims at characterizing the accretion properties of several hundred members of the star-forming region NGC 2264 (3Myr). We performed a deep u,g,r,i mapping of the... -
Magnetic field in V2052 Oph
V2052 Oph is a {beta} Cep star with vsini~60km/s. The behavior of its stellar wind was studied in the ultraviolet wavelength region with the IUE satellite. It revealed periodic... -
X-ray emission in cool main sequence stars
The maximum amplitude A_max_ of spot-induced brightness variations from long-term V-band photometry and the ratio L_X_/L_bol_ between X-ray and bolometric luminosities are... -
Rotation and magnetic field in omega Ori
Omega Ori is a B2IIIe star for which rotational modulation and non-radial pulsations (NRP) have been recently investigated from two independent observational campaigns in 1998... -
Catalogue of stellar effective magnetic fields
We present the catalogue of averaged quadratic effective magnetic fields for 596 main sequence and giant stars. The catalogue is derived from measurements of the stellar... -
Pulse-time history of PSR B0540-69
A pulse-time history of PSR B0540-69 is reported, based on the analysis of an extended data set including ASCA, BeppoSAX and RXTE observations spanning a time interval of about... -
Photometric standards around gravitational lenses
We present a catalog of secondary photometric standard stars in the neighborhood of 14 gravitationally lensed quasars. These stars were verified to be non variable using... -
Pulsar Catalog
This database is based on the 1995 May 3 electronic version of the Taylor et al. Pulsar Catalog and contains data on 706 pulsars, i.e., it contains 25% more entries than the... -
Parkes Multibeam Survey New Pulsar Catalog
The Parkes Multibeam (PM) Pulsar Survey uses the 20 cm multibeam receiver system and multibeam filter banks, digitizer and data-acquisition system to survey a region within |b|... -
Fermi LAT Second Catalog of Gamma-Ray Pulsars (2PC)
This catalog summarizes 0.1 GeV gamma-ray pulsar detections using data acquired by the Large Area Telescope (LAT) on the Fermi satellite. These pulsars are neutron stars... -
Crab Pulsar Timing
The CRABTIME database contains the Crab Pulsar Monthly Ephemeris covering the period from Feb 15 1982 (MJD=45015) to (close to) the present that was created Dr. Andrew Lyne and... -
CGRO/BATSE Pulsar Observations
BATSE data are divided into four groups: trigger, daily, occultation, and pulsar. Each group has structured directories beneath it containing data ordered by an appropriate...
