Long-term multi-wavelength study of 1ES 0647+250
MAGIC Collaboration, V. A. Acciari, T. Aniello +217
The BL Lac object 1ES 0647+250 is one of the few distant -ray emitting blazars detected at very high energies (VHE, 100 GeV) during a non-flaring state. It was detected…
A multiband study and exploration of the radio wave - -ray connection in 3C 84
G. F. Paraschos, V. Mpisketzis, J. -Y. Kim +8
Total intensity variability light curves offer a unique insight into the ongoing debate about the launching mechanism of jets. For this work, we utilise the availability of radio a…
Experimental Investigation of Drain Noise in High Electron Mobility Transistors: Thermal and Hot Electron Noise
Bekari Gabritchidze, Kieran A. Cleary, Anthony C. Readhead +1
We report the on-wafer characterization of -parameters and microwave noise temperature () of discrete metamorphic InGaAs high electron mobility transistors (mHEMTs) at 4…
WALOP-South: A Four-Camera One-Shot Imaging Polarimeter for PASIPHAE Survey. Paper II -- Polarimetric Modelling and Calibration
Siddharth Maharana, Ramya M. Anche, A. N. Ramaprakash +22
The Wide-Area Linear Optical Polarimeter (WALOP)-South instrument is an upcoming wide-field and high-accuracy optical polarimeter to be used as a survey instrument for carrying out…
The hunt for extraterrestrial high-energy neutrino counterparts
I. Liodakis, T. Hovatta, V. Pavlidou +7
The origin of Petaelectronvolt (PeV) astrophysical neutrinos is fundamental to our understanding of the high-energy Universe. Apart from the technical challenges of operating detec…
Starlight-polarization-based tomography of the magnetized interstellar medium: PASIPHAE's line-of-sight inversion method
V. Pelgrims, G. V. Panopoulou, K. Tassis +20
We present the first Bayesian method for tomographic decomposition of the plane-of-sky orientation of the magnetic field with the use of stellar polarimetry and distance. This stan…
Jet kinematics in the transversely stratified jet of 3C 84 A two-decade overview
G. F. Paraschos, T. P. Krichbaum, J. -Y. Kim +11
3C84 (NGC1275) is one of the brightest radio sources in the mm radio-bands, which led to a plethora of VLBI observations at numerous frequencies over the years. They reveal a two-s…
Self-heating of cryogenic high-electron-mobility transistor amplifiers and the limits of microwave noise performance
Anthony J. Ardizzi, Alexander Y. Choi, Bekari Gabritchidze +4
The fundamental limits of the microwave noise performance of high electron mobility transistors (HEMTs) are of scientific and practical interest for applications in radio astronomy…
Investigating the blazar TXS 0506+056 through sharp multi-wavelength eyes during 2017-2019
MAGIC Collaboration, V. A. Acciari, T. Aniello +213
The blazar TXS 0506+056 got into the spotlight of the astrophysical community in September 2017, when a high-energy neutrino detected by IceCube (IceCube-170922A) was associated at…
Multiwavelength variability power spectrum analysis of the blazars 3C 279 and PKS 1510-089 on multiple timescales
Arti Goyal, Marian Soida, Lukasz Stawarz +24
We present the results of variability power spectral density (PSD) analysis using multiwavelength radio to GeV\,-ray light curves covering decades/years to days/minutes timescal…
New Tests of Millilensing in the Blazar PKS 1413+135
A. L. Peirson, I. Liodakis, A. C. S. Readhead +26
Symmetric Achromatic Variability (SAV) is a rare form of radio variability in blazars that has been attributed to gravitational millilensing by a ~ mass cond…
