The Low Frequency Array (LOFAR) is uniquely able to perform deep, high- resolution imaging at frequencies below 100MHz. Observations in this regime, using the Low Band Antenna...

Recent studies using Gaia data have reported tidal tail detections for tens to hundreds of open clusters. However, a comprehensive assessment of the reliability and completeness...

Stellar rotation is a fundamental parameter in studies of the formation and evolution of stars. However, large homogeneous catalogues of rotational velocities derived from...

The accretion luminosity (Lacc) in young, low-mass stars is crucial for understanding stellar formation. However, obtaining direct measurements is often hindered by limited...

TOI-282 is a bright (V=9.38) F8 main-sequence star known to host three transiting long-period (Pb=22.9d, Pc=56.0d, Pd=84.3d) small (Rp~=2-4R_{Earth}) planets. The orbital period...

The flat-spectrum radio quasar (FSRQ) 4C +01.28 is a bright and highly variable radio and gamma-ray emitter. We aim to pinpoint the location of the gamma-ray emitting region...

We present wide-field upgraded Giant Metrewave Radio Telescope (uGMRT) images of the fields around the X-shaped radio galaxies (XRGs) 4C32.25, 4C61.23, and MRC 2011-298 obtained...

Identifying the progenitors of thermonuclear supernovae (Type Ia supernovae; SNe Ia) remains a key objective in contemporary astronomy. The rare subclass of SNe Ia-CSM that...

The “Orbita” Radio Polygon at an altitude of 2750 meters conducts solar radio emission observations using state-of-the-art equipment. This includes instruments for monitoring...

We present new time-series CCD VR photometry of the globular cluster NGC 5634. We aim to use the known RR Lyrae stars, members of the cluster, as indicators of mean metallicity...

A combination of spectroscopic and photometric observations provides an excellent data sample for studying stellar chromospheric activity. We have combined LAMOST...

We present SpiderCat, a multiwavelength catalog of all publicly known compact binary millisecond pulsars (MSPs) in the Galactic field. These systems, colloquially known as...

We present the stellar parameters and chemical abundances of 30 elements for five stars located at large radii (3.5-10.7 times the half-light radius) in the Sextans dwarf...

Most active galactic nuclei (AGN) are believed to be surrounded by a dusty molecular torus on the parsec scale, which is often embedded within a larger circumnuclear disk (CND)....

Despite its critical importance for determining stellar properties and evolution, the origin and physical nature of microturbulence remains poorly understood. Most of the...

This table records high-level information for each Swift observation and provides access to the data archive. Each record is associated with a single observation that contains...

The ObsCore VizieR table gather FITS images, spectra and time-series into a single table. The contents are the VizieR associated data, publilished in original article with the...

We present an extensive, panchromatic photometric (UV, optical, and near-IR) and low-resolution optical spectroscopic coverage of a Type IIP supernova SN 2018gj that occurred on...

We present the results of our ALMA<~0.5kpc resolution dense molecular line (HCN and HCO^+^J=2-1, J=3-2, and J=4-3) observations of 12 nearby (ultra)luminous infrared galaxies...

Identifying trends between observational data and the range of physical parameters of massive stars is a critical step to the still-elusive full understanding of the source,...
