Non-thermal emission from fall-back clouds in the Broad-Line Region of Active Galactic Nuclei
Ana Laura Müller, Mohammad-Hassan Naddaf, Michal Zajaček +3
The spectra of active galactic nuclei exhibit broad-emission lines that presumably originate in the Broad-Line Region (BLR) with gaseous-dusty clouds in a predominantly Keplerian m…
Multi-wavelength temporal and spectral analysis of Blazar S5 1803+78
Shruti Priya, Raj Prince, A. Agarwal +3
Blazars are a class of AGN, one of their jets is pointed towards the earth. Here, we report about the multi-wavelength study for blazar S5 1803+78 between MJD 58727 to MJD 59419. W…
Galaxy And Mass Assembly (GAMA): Self-Organizing Map Application on Nearby Galaxies
B. W. Holwerda, Dominic Smith, Lori Porter +12
Galaxy populations show bimodality in a variety of properties: stellar mass, colour, specific star-formation rate, size, and Sérsic index. These parameters are our feature space. W…
Deep ASKAP EMU Survey of the GAMA23 field: Properties of radio sources
Gülay Gürkan, I. Prandoni, A. O'Brien +19
We present the Australian Square Kilometre Array Pathfinder (ASKAP) observations of the Galaxy and Mass Assembly (GAMA)-23h field. The survey was carried out at 887.5 MHz and cover…
Black holes at cosmic dawn in the redshifted 21cm signal of HI
I. Felix Mirabel, Luis F. Rodriguez
Indirect insights of Pop III stars and Black Holes (BHs) at Cosmic Dawn (CD) may be imprinted as an absorption signal in the 21cm line of HI against the CMB, when the Universe was…
The LOFAR Two-metre Sky Survey -- V. Second data release
T. W. Shimwell, M. J. Hardcastle, C. Tasse +103
In this data release from the LOFAR Two-metre Sky Survey (LoTSS) we present 120-168MHz images covering 27% of the northern sky. Our coverage is split into two regions centred at ap…
