ACES VII. Compact Continuum Source Catalog of the Central Molecular Zone
Jennifer Wallace, Cara Battersby, Nazar Budaiev +58
The Central Molecular Zone (CMZ) resides in the inner few hundred parsecs of our Galaxy, and despite being the largest reservoir of dense molecular gas in the Milky Way, it has a r…
Polytropic stellar wind models with strongly localized heating
L. Westrich, B. Shergelashvili, H. Fichtner +1
Polytropic models of stellar winds remain to be useful tools because they allow for a simple description of the energy balance of the expanding plasma without explicitly specifying…
Joining forces: 30 years of optical monitoring of the Einstein Cross
V. N. Shalyapin, L. J. Goicoechea, R. Gil-Merino +5
We present an extended optical monitoring of the quadruply-imaged gravitationally lensed quasar QSO 2237+0305, the Einstein Cross, including observations from different observatori…
NGC 3521 as the Milky Way near twin: spectral energy distribution from UV to radio decameter ranges
O. V. Kompaniiets, I. B. Vavilova, Y. V. Vasylkivskyi +10
Milky Way analogues (MWAs) are usually selected from structural and kinematic properties, but robust SED-based similarity criteria are limited by heterogeneous photometry and incom…
Galaxy rotation curve based on RGB stars from the Gaia DR3 catalogue
P. N. Fedorov, A. M. Dmytrenko, V. S. Akhmetov +8
In this paper, we construct a detailed circular velocity curve of the Milky Way out to 20 kpc based on the radial component of the Jeans equation in cylindrical coordinates, assumi…
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…
CoSEE-Cat: A Comprehensive Solar Energetic Electron event Catalogue obtained from combined in situ and remote-sensing observations from Solar Orbiter -- Catalogue description and first statistical results
A. Warmuth, F. Schuller, R. Gómez-Herrero +39
(abridged) The acceleration of particles at the Sun and their propagation through interplanetary space are key topics in heliophysics. Specifically, solar energetic electrons (SEEs…
Observations of Carbon Radio Recombination Lines with the NenuFAR telescope. I. Cassiopeia A and Cygnus A
Lucie Cros, Antoine Gusdorf, Philippe Salomé +26
Carbon Radio Recombination Lines (CRRLs) at decametre wavelengths trace the diffuse phase of the interstellar medium (ISM) of the Galaxy. Their observation allows to measure physic…
Evidence of the Earth's inner radiation belts during the low Solar and geomagnetic activity obtained with the STEP-F instrument
O. V. Dudnik, O. V. Yakovlev
Purpose: The subject of research is the spatio-temporal charged particles in the Earth's magnetosphere outside the South Atlantic magnetic Anomaly during the 11-year cycle of solar…
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…
Optical+NIR analysis of a Newly Confirmed Einstein ring at z1 from the Kilo-Degree Survey: Dark matter fraction, total and dark matter density slope and IMF
Rui Li, Nicola R. Napolitano, Giuseppe D Ago +16
We report the spectroscopic confirmation of a bright blue Einstein ring in the Kilo Degree Survey (KiDS) footprint: the Einstein ``blue eye''. Spectroscopic data from X-Shooter at…
Investigation of the rotational spectrum of CHOH and its tentative detection toward Sagittarius B2(N)
Holger S. P. Müller, Vadim V. Ilyushin, Arnaud Belloche +2
Methanol is an abundant molecule in space. The column density of CHOH is in some star-forming regions so high that the search for CHOH is promising. But only very…
Rotational spectroscopy of CHOD with a reanalysis of CHOD toward IRAS 162932422
V. V. Ilyushin, H. S. P. Müller, M. N. Drozdovskaya +10
We have started a measurement campaign of numerous methanol isotopologs in low-lying torsional states in order to provide extensive line lists for radio astronomical observations f…
On the Possibility of Detecting a Global Signal in the Line of the Hyperfine Structure of Hydrogen from the Dark Ages
Olexandr Konovalenko, Vyacheslav Zakharenko, Bohdan Novosyadlyj +7
We analyze the possibilities of detecting a signal in the hydrogen 21~cm line, which was formed in the early Universe during the the Dark Ages cosmological epoch, using the Ukraini…
Using a Metasurface to Enhance the Radiation Efficiency of Subterahertz Antennas Printed on Thick Substrates
Yevhen M. Yashchyshyn, Peter L. Tokarsky
This study investigates the possibility of increasing the radiation efficiency of printed antennas and arrays by suppressing their inherent surface waves using a metasurface made o…
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…
