On the basis of analysis of original publications and our own measurements a Cataloque of magnetic chemically peculiar (CP) upper-main sequence stars has been established. The...

Starspots are created by local magnetic fields on the surfaces of stars, just as sunspots. Their fields are strong enough to suppress the overturning convective motion and thus...

We present a sample of over 100 highly X-ray luminous galaxy clusters (L_X,0.1-2.4keV_~10^45^erg/s) at z~0.5-0.9, discovered by the extended Massive Cluster Survey (eMACS) in...

SDSS-V is carrying out a dedicated survey for white dwarfs, single and in binaries, and we report the analysis of the spectroscopy of 504 cataclysmic variables (CVs) and CV...

We present initial results from the Polarisation Sky Survey of the Universe's Magnetism (POSSUM), analyzing 22817 Faraday Rotation Measures (RMs) with median uncertainties of...

A key event in the history of the Milky Way is the formation of the bar. This event affects the subsequent structural and dynamical evolution of the entire Galaxy. When the bar...

We use an updated method for the detection of double-lined spectroscopic binaries (SB2s) using vsini values from spectral fits. The method is applied to all spectra from Large...

Spectropolarimetric data allow for simultaneous monitoring of stellar chromospheric logR'HK activity and the surface-averaged longitudinal magnetic field, Bl, giving the...

The Lynds' Dark Nebula (LDN) 1615/1616 and CB 28 (hereafter L1616) together form a cometary globule located at an angular distance of about 8{deg} west of the Orion OB1...

Numerous magnetic hot stars exhibit gyrosynchrotron radio emission. The source electrons were previously thought to be accelerated to relativistic velocities in the current...

Eccentricity of wide binaries is difficult to measure due to their long orbital periods. With Gaia's high-precision astrometric measurements, eccentricity of a wide binary can...

We present a comprehensive census of X-ray millisecond pulsars (MSPs) in 29 Galactic globular clusters (GCs), including 68 MSPs with confirmed X-ray luminosities and 107 MSPs...

Distance versus dispersion measure relations are constructed for Galactic radio pulsars in small solid angle intervals. The calculations are based on some basic criteria, as...

Young exoplanets and their corresponding host stars are fascinating laboratories for constraining the time-scale of planetary evolution and planet-star interactions. However,...

Fast radio bursts (FRBs) are mysterious millisecond pulses in radio, most of which originate from distant galaxies. Revealing the origin of FRBs is becoming central in...

Optical and infrared polarization mapping and recent Planck observations of the filamentary cloud L1495 in Taurus show that the large-scale magnetic field is approximately...

In this paper, we present the third data release (DR3) of the Herschel Astrophysical Terahertz Large Area Survey (H-ATLAS). We identify likely near- infrared counterparts to...

We present pulse width measurements for a sample of radio pulsars observed with the MeerKAT telescope as part of the Thousand-Pulsar-Array (TPA) programme in the MeerTime...

Faraday rotation measures (RMs) should be interpreted with caution because there could be multiple magneto-ionized medium components that contribute to the net Faraday rotation...

Most ultraluminous X-ray sources (ULXs) are thought to be powered by super- Eddington accretion on to stellar-mass compact objects. Accretors in this extreme regime are...
