A radio view on Gamma-Loud Protostars: Derivation of jet mechanical luminosity
Javier Méndez-Gallego, Carlos Carrasco-González, Rubén López-Coto +5
Context. Gamma-Loud Protostars (GLPs) have been recently reported as Galactic hadronic accelerators whose acceleration site is situated in their protostellar jets. Theoretical and…
Where within the 3C 84 jet are -rays produced?
Georgios F. Paraschos, Ioannis Liodakis, Svetlana Jorstad +49
The location of -ray creation and emission within extra-galactic jets is a matter of active debate. One particularly well-suited source to pinpoint the location is the nearby, b…
Monitoring of 3C 286 with ALMA, IRAM, and SMA from 2006 to 2025: Stability, Synchrotron Ages, and Frequency-Dependent Polarization Attributed to Core-Shift
Minchul Kam, Hiroshi Nagai, Motoki Kino +23
We present the results of multi-frequency monitoring of the radio quasar 3C 286, conducted using three instruments: ALMA at 91.5, 103.5, 233.0, and 343.4 GHz, the IRAM 30-m Telesco…
Gamma-ray flares from the jet of the blazar CTA 102 in 2016-2018
Sanghyun Kim, Sang-Sung Lee, Juan Carlos Algaba +16
CTA 102 is a -ray bright blazar that exhibited multiple flares in observations by the Large Area Telescope on board the Fermi Gamma-Ray Space Telescope during the period of 2016…
A Near Magnetic-to-kinetic Energy Equipartition Flare from the Relativistic Jet in AO 0235+164 during 2013-2019
Whee Yeon Cheong, Sang-Sung Lee, Sang-Hyun Kim +17
We present the multiwavelength flaring activity of the blazar AO 0235+164 during its recent active period from 2013 to 2019. From a discrete correlation function (DCF) analysis, we…
Sensitivity of the Cherenkov Telescope Array to TeV photon emission from the Large Magellanic Cloud
The Cherenkov Telescope Array Consortium
A deep survey of the Large Magellanic Cloud at ~0.1-100TeV photon energies with the Cherenkov Telescope Array is planned. We assess the detection prospects based on a model for the…
Magnetic Field Strengths of the Synchrotron Self-Absorption Region in the Jet of CTA 102 During Radio Flares
Sang-Hyun Kim, Sang-Sung Lee, Jee Won Lee +15
CTA 102 is a blazar implying that its relativistic jet points towards Earth and emits synchrotron radiation produced by energetic particles gyrating in the magnetic field. This stu…
Exploring the connection between parsec-scale jet activity and broadband outbursts in 3C 279
B. Rani, S. G. Jorstad, A. P. Marscher +16
We use a combination of high-resolution very long baseline interferometry (VLBI) radio and multi-wavelength flux density and polarization observations to constrain the physics of t…
POLAMI: Polarimetric Monitoring of Active Galactic Nuclei at Millimetre Wavelengths. III. Characterisation of total flux density and polarisation variability of relativistic jets
Ivan Agudo, Clemens Thum, Venkatessh Ramakrishnan +3
We report on the first results of the POLAMI program, a simultaneous 3.5 and 1.3mm full-Stokes-polarisation monitoring of a sample of 36 of the brightest active galactic nuclei in…
POLAMI: Polarimetric Monitoring of Active Galactic Nuclei at Millimetre Wavelengths. II. Widespread circular polarisation
Clemens Thum, Ivan Agudo, Sol N. Molina +5
We analyse the circular polarisation data accumulated in the first 7 years of the POLAMI project introduced in an accompanying paper (Agudo et al.). In the 3mm wavelength band, we…
