We present the first degree-scale tomography map of the dusty magnetized interstellar medium (ISM) from stellar polarimetry and distance measurements. We used the RoboPol...

Single-pointing observations of NH_3_(1,1) and (2,2) were conducted toward 672 Planck Early Cold Cores (ECCs) using the Nanshan 26-m radio telescope. Out of these sources, a...

The physical properties, evolution, and fragmentation of massive dense cores (MDCs, ~0.1pc) are fundamental to the understanding of high-mass star formation. We aim at...

The archive of digitized plates obtained on Wide aperture Maksutov meniscus telescope with main mirror 50 cm at the Fesenkov Astrophysical Institute (FAI), Almaty, Kazakhstan....

The archive of digitized plates obtained on Schmidt telescope (large camera) at the Fesenkov Astrophysical Institute (FAI), Almaty, Kazakhstan. They represent the results of...

A spatially resolved cicrumstellar disk spectrum and composition can provide valuable insights into the bulk composition of forming planets, as well as the mineralogical...

The MeerKAT Absorption Line Survey (MALS) has observed 391 telescope pointings at the L band (900-1670MHz) at {delta}<~+20{deg}. We present radio continuum images and a...

Here we describe a new study of the supernova remnants (SNRs) and SNR candidates in nearby face-on spiral galaxy M83, based primarily on MUSE integral field spectroscopy. Our...

The star-forming region W5 is a major part of the Cassiopeia OB6 association. Its internal structure and kinematics may provide hints of the star formation process in this...

The observed diversity of exoplanets can possibly be traced back to the planet formation processes. Planet-disk interactions induce sub-structures in the circumstellar disk that...

The calibration of optical polarimeters relies on the use of stars with negligible polarization (i.e., unpolarized standard stars) for determining the instrumental polarization...

We use photometric and kinematic data from Gaia DR2 to explore the structure of the star-forming region associated with the molecular cloud of Perseus. Apart from the two...

Observed changes in protostellar brightness can be complicated to interpret. In our James Clerk Maxwell Telescope (JCMT) Transient Monitoring Survey, we discovered that a young...

Maser flares are of particular significance for the study of massive star formation as they not only signal but also provide unique insights into transient phenomena such as...

We model the evolution of active galactic nuclei (AGN) by constructing their radio LFs. We used a set of surveys of varying area and depth, namely, the deep COSMOS survey of...

There are significant amounts of H_2_ in the Milky Way. Due to its symmetry H_2_ does not radiate at radio frequencies. CO is thought to be a tracer for H_2_, however CO is...

Accretion is one of the defining characteristics of classical T Tauri stars, fueled by the presence of a circumstellar disk comprised of dust and gas. Accretion produces a UV...

This catalog contains near-infrared (2.5--5.0 micron) low-resolution (R ~ 100) spectra of 72 Galactic Planetary Nebulae (PNe), obtained with the InfraRed Camera (IRC) onboard...

The VSOP (VLBI Space Observatory Programme) mission was led by the Institute of Space and Astronautical Science, in collaboration with the National Astronomical Observatory of...

The SVO EXPORT Herbig AeBe SSAP service gives access to a homogeneous spectroscopic database of HAeBe stars. It consists of 337 multi-epoch optical spectra of 38 object observed...
