Proper motion and brightness changes of Cas A at 5GHz
The study on the dynamic evolution of young supernova remnants (SNRs) is an important way to understand the density structure of the progenitor's circumstellar medium. We have... -
Radio quasars study from Radio/X-ray surveys
We examine the Fundamental Plane of black hole activity for correlations with redshift and radio loudness in both radio-loud and radio-quiet quasar populations. Sources are... -
MAVERIC radio continuum sources from 26 GCs
Radio continuum observations offer a new window on compact objects in globular clusters compared to typical X-ray or optical studies. As part of the MAVERIC survey, we have used... -
MOMO. VI. Radio variability of OJ 287
Based on our dedicated Swift monitoring program, MOMO, OJ 287 is one of the best-monitored blazars in the X-ray-UV-optical regime. Here, we report results from our accompanying,... -
Fermi jetted AGN with reliable redshift
We collect a large sample with a reliable redshift detected by the Fermi satellite after 10yr of data (4FGL-DR2), including blazars, gamma-ray narrow-line Seyfert 1 galaxies... -
BTFR's study of ~10000 HyperLEDA galaxies
The interstellar gas in spiral galaxies can constitute a significant fraction of the baryon mass and it has been demonstrated that the sum of stellar and gas components... -
Study of massive SMBHs hosted by FSRQs
We present the space density evolution, from z = 1.5 up to z = 5.5, of the most massive (M => 10^9^ M_{sun}) black holes hosted in jetted active galactic nuclei (AGNs). The... -
Study of galactic PSRs mainly from ATNF
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... -
New identifications of 4FGL sources with SPT-SZ
The fourth Fermi Large Area Telescope catalog (4FGL) contains 5064 {gamma}-ray sources detected at high significance, but 26% of them still lack associations at other... -
LoTSS DR2 restarted radio galaxies in HETDEX field
Recurrent phases of dormancy and activity occur in the supermassive black holes in active galactic nuclei. Characterizing the duty cycles of this process is crucial in... -
Ccold molecular gas depletion in AGN hosts
The energy released by active galactic nuclei (AGN) has the potential to heat or remove the gas of the ISM, thus likely impacting the cold molecular gas reservoir of host... -
Study of CSS/GPS/MPS radio sources
In this work, we study the optical properties of compact radio sources selected from the literature in order to determine the impact of the radio-jet in their circumnuclear... -
OJ 287 polarisation in radio, mm and optical
OJ 287 is a bright blazar with century-long observations, and one of the strongest candidates to host a supermassive black hole binary. Its polarisation behaviour between 2015... -
Mrk 421 multiwavelength variability
Mrk 421 was in its most active state around early 2010, which led to the highest TeV gamma-ray flux ever recorded from any active galactic nuclei (AGN). We aim to characterize... -
Multiwavelength ctp of Fermi gamma-ray sources
In this paper, we searched for multi-wavelength (X-ray, optical and radio) counterparts to the unassociated gamma-ray sources (UGS) of the Fermi 4FGL-DR4 catalog. The main goal... -
ATOMS ALMA 3 mm VII SiO clumps with ACA
To understand the nature of SiO emission, we conducted ACA observations of the SiO (2-1) lines toward 146 massive star-forming regions, as part of the ALMA Three-millimeter... -
New CHIME/FRB I catalogue updates released
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... -
CO-CHANGES II.
Molecular gas, as the fuel for star formation, and its relationship with atomic gas are crucial for understanding how galaxies regulate their star forming (SF) activities. We... -
NESMP sources main variability characteristics
Compact radio sources can show remarkable flux density variations at GHz frequencies on a wide range of timescales. The origin of the variability is a mix of source-intrinsic... -
Catalogue of Radio Stars
The first version of this catalogue was published in Abh.Hamburger Sternw. 1978, Vol.10, p 1ff. (CDS Catalogue II/129). A second version was published in 1987...
