Ukrainian Wartime Astronomy and its Prospects
Danilo Albergaria, Kateryna Frantseva, Pedro Russo +20
The Russian invasion of Ukraine damaged or compromised astronomical facilities and has prompted the displacement of researchers. A plan to restore Ukrainian astronomy, rooted in a…
Near-field imaging of local interference in radio interferometric data: Impact on the redshifted 21 cm power spectrum
S. Munshi, F. G. Mertens, L. V. E. Koopmans +24
Radio-frequency interference (RFI) is a major systematic limitation in radio astronomy, particularly for science cases requiring high sensitivity, such as 21 cm cosmology. Traditio…
Multi-antenna probing of absorbing regions inside and outside Cassiopeia A
Lev A. Stanislavsky, Ihor N. Bubnov, Aleksander A. Stanislavsky +6
Context. Cassiopeia A occupies an important place among supernova remnants (SNRs) in low-frequency radio astronomy. The analysis of its continuum spectrum from low frequency observ…
Preserving your skies since 1988 -- Committee on Radio Astronomy Frequencies (CRAF) -- Periodic Review 2011-2021
Committee on Radio Astronomy Frequencies, Benjamin Winkel, Simon Garrington +43
The Committee on Radio Astronomy Frequencies (CRAF) is an Expert Committee of the European Science Foundation. It aims to provide a cost-effective single voice on frequency protect…
Roman CCS White Paper: Characterizing the Galactic population of isolated black holes
Casey Y. Lam, Natasha Abrams, Jeff Andrews +34
Although there are estimated to be 100 million isolated black holes (BHs) in the Milky Way, only one has been found so far, resulting in significant uncertainty about their propert…
The first detection of the solar U+III association with an antenna prototype for the future lunar observatory
Lev Stanislavsky, Igor Bubnov, Alexander Konovalenko +2
We report about observations of the solar U+III bursts on 5 June of 2020 by means of a new active antenna designed to receive radiation in 4-70 MHz. This instrument can serve as a…
Pulsars with NenuFAR: backend and pipelines
L. Bondonneau, J. -M. Grießmeier, G. Theureau +27
NenuFAR (New extension in Nançay upgrading LoFAR) is a new radio telescope developed and built on the site of the Nançay Radio Observatory. It is designed to observe the largely un…
Calibration of RADMON Radiation Monitor Onboard Aalto-1 CubeSat
Philipp Oleynik, Rami Vainio, Arttu Punkkinen +11
RADMON is a small radiation monitor designed and assembled by students of the University of Turku and the University of Helsinki. It is flown on-board Aalto-1, a 3-unit CubeSat in…
Rotational spectroscopy of methyl mercaptan CHSH at millimeter and submillimeter wavelengths
O. Zakharenko, V. V. Ilyushin, F. Lewen +8
We present a new global study of the millimeter (mm) wave, submillimeter (sub-mm) wave, and terahertz (THz) spectra of the lowest three torsional states of methyl mercaptan (CH…
Solar bursts as can be observed from the lunar farside with a single antenna at very low frequencies
A. A. Stanislavsky, A. A. Konovalenko, S. N. Yerin +10
Earth-based observations are complicated by the opacity of Earth's ionosphere at very low frequencies and strong man-made radio frequency interference. This explains long standing…
A simple method to determine the time delays in presence of microlensing: application to HE 0435-1223 and PG1115+080
V. S. Tsvetkova, V. M. Shulga, L. A. Berdina
A method for determining the time delays in gravitationally lensed quasars is proposed, which offers a simple and transparent procedure to mitigate the effects of microlensing. The…
Separating Nightside Interplanetary and Ionospheric Scintillation with LOFAR
R. A. Fallows, M. M. Bisi, B. Forte +4
Observation of interplanetary scintillation (IPS) beyond Earth-orbit can be challenging due to the necessity to use low radio frequencies at which scintillation due to the ionosphe…
RadioAstron -- a Telescope with a Size of 300 000 km: Main Parameters and First Observational Results
N. S. Kardashev, V. V. Khartov, RadioAstron collaboration
The Russian Academy of Sciences and Federal Space Agency, together with the participation of many international organizations, worked toward the launch of the RadioAstron orbiting…
Heliograph of the UTR-2 Radio Telescope
Aleksander Stanislavsky, Artem Koval, Aleksander Konovalenko +1
The broadband analog-digital heliograph based on the UTR-2 radio telescope is described in detail. This device operates by employing the parallel-series principle when five equi-sp…
Antenna Performance Analysis for Decameter Solar Radio Observations
Aleksander Stanislavsky, Aleksander Konovalenko, Eduard Abranin +5
Decameter wavelength radio emission is finely structured in solar bursts. For their research it is very important to use a sufficient sensitivity of antenna systems. In this paper…
Beam propagation in a Randomly Inhomogeneous Medium
Aleksander Stanislavsky
An integro-differential equation describing the angular distribution of beams is analyzed for a medium with random inhomogeneities. Beams are trapped because inhomogeneities give r…
