Correlation between active regions' spectra at high radio frequencies and solar flare occurrences
Sara Mulas, Alberto Pellizzoni, Marco Marongiu +31
High radio frequencies observations with the Italian network of large single-dish radio telescopes resulted in ~450 solar images between 2018 and 2023 in K-band frequency range (18…
A long-term multiwavelength study of the flat spectrum radio quasar OP 313
Chiara Bartolini, Elina Lindfors, Andrea Tramacere +25
The Flat Spectrum Radio Quasar OP 313 is a high-redshift (z = 0.997) blazar that entered an intense gamma-ray active phase from November 2023 to March 2024, as observed by the Larg…
First detection of VHE gamma-ray signal from the FSRQ TON 0599
MAGIC Collaboration, K. Abe, S. Abe +245
TON\,0599 (z=0.7247) belongs to the few flat spectrum radio quasars (FSRQs) detected in the very high energy (VHE, \,GeV) gamma-ray band. Its redshift makes it currently o…
Study of solar brightness profiles in the 18-26 GHz frequency range with INAF radio telescopes II. Evidence for coronal emission
M. Marongiu, A. Pellizzoni, S. Righini +43
One of the most important objectives of solar physics is the physical understanding of the solar atmosphere, the structure of which is also described in terms of the density (N) an…
Study of solar brightness profiles in the 18-26 GHz frequency range with INAF radio telescopes I: solar radius
M. Marongiu, A. Pellizzoni, S. Mulas +32
The Sun is an extraordinary workbench, from which several fundamental astronomical parameters can be measured with high precision. Among these parameters, the solar radius $R_{\odo…
Multi-wavelength observations of the lensed quasar PKS 1830211 during the 2019 -ray flare
S. Vercellone, I. Donnarumma, C. Pittori +32
PKS 1830211 is a -ray emitting, high-redshift (z ), lensed flat-spectrum radio quasar. During the period mid-February to mid-April 2019, this source underw…
Tracking the X-ray Polarization of the Black Hole Transient Swift J1727.8-1613 during a State Transition
Adam Ingram, Niek Bollemeijer, Alexandra Veledina +120
We report on an observational campaign on the bright black hole X-ray binary Swift J1727.81613 centered around five observations by the Imaging X-ray Polarimetry Explorer (IXPE)…
New high-frequency radio observations of the Cygnus Loop supernova remnant with the Italian radio telescopes
S. Loru, A. Pellizzoni, E. Egron +19
Supernova remnants (SNRs) represent a powerful laboratory to study the Cosmic-Ray acceleration processes at the shocks, and their relation to the properties of the circumstellar me…
A flat-spectrum flare in S4 0444+63 revealed by a new implementation of multi-wavelength single-dish observations
Marcello Giroletti, Simona Righini
Relativistic amplification boosts the contribution of the jet base to the total emission in blazars, thus making single dish observations useful and practical to characterise their…
FBQS J1644+2619: multiwavelength properties and its place in the class of gamma-ray emitting Narrow Line Seyfert 1s
J. Larsson, F. D'Ammando, S. Falocco +4
A small fraction of Narrow Line Seyfert 1s (NLSy1s) are observed to be gamma-ray emitters. Understanding the properties of these sources is of interest since the majority of NLSy1s…
Single-dish and VLBI observations of Cygnus X-3 during the 2016 giant flare episode
E. Egron, A. Pellizzoni, M. Giroletti +34
In September 2016, the microquasar Cygnus X-3 underwent a giant radio flare, which was monitored for 6 days with the Medicina Radio Astronomical Station and the Sardinia Radio Tele…
Imaging of SNR IC443 and W44 with the Sardinia Radio Telescope at 1.5 GHz and 7 GHz
E. Egron, A. Pellizzoni, M. N. Iacolina +33
Observations of supernova remnants (SNRs) are a powerful tool for investigating the later stages of stellar evolution, the properties of the ambient interstellar medium, and the ph…
The Sardinia Radio Telescope: From a Technological Project to a Radio Observatory
I. Prandoni, M. Murgia, A. Tarchi +43
[Abridged] The Sardinia Radio Telescope (SRT) is the new 64-m dish operated by INAF (Italy). Its active surface will allow us to observe at frequencies of up to 116 GHz. At the mom…
