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…

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…

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…
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…
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…
A new kinematic model of the Galaxy: analysis of the stellar velocity field from Gaia Data Release 3
V. S. Akhmetov, B. Bucciarelli, M. Crosta +4
This work presents the results of a kinematic analysis of the Galaxy that uses a new model as applied to the newest available Gaia data. We carry out the Taylor decomposition of th…
Mapping the kinematic parameters of the Galaxy from the Gaia EDR3 red giants and sub-giants
P. N. Fedorov, V. S. Akhmetov, A. B. Velichko +2
We present the results of a kinematic analysis of red giants and subgiants whose centroids are in the plane of our Galaxy. For this, the positions, parallaxes, proper motions, and…
Apparent counter-rotation in the torus of NGC 1068: influence of an asymmetric wind
Elena Yu. Bannikova, Nina A. Akerman, Massimo Capaccioli +3
The recent ALMA maps together with observations of HO maser emission seem to suggest the presence of a counter-rotation in the obscuring torus of NGC 1068. We propose to explai…
Rotational and rovibrational spectroscopy of CDOH with an account of CDOH toward IRAS 162932422
V. V. Ilyushin, H. S. P. Müller, J. K. Jørgensen +10
Solar-type protostars harbor highly deuterated complex organics. While this degree of deuteration may provide important clues in studying the formation of these species, spectrosco…
Propionamide (C2H5CONH2): The largest peptide-like molecule in space
Juan Li, Junzhi Wang, Xing Lu +16
Peptide bonds, as the molecular bridges that connect amino acids, are crucial to the formation of proteins. Searches and studies of molecules with embedded peptide-like bonds are t…
New ex-OH maser detections in the northern celestial hemisphere
O. Patoka, O. Antyufeyev, I. Shmeld +5
Aims.Molecular masers, including methanol and hydroxyl masers, and in particular the ones in excited rotational states (ex-OHmasers), are one of the most informative tools for stud…
Analysis of modern astrometric catalogues in the Gaia era
V. S. Akhmetov, P. N. Fedorov, V. S. Tsvetkova +1
We investigate of the systems of proper motions of stars in the ground-based catalogues HSOY, UCAC5, GPS1 and PMA derived by combining with the Gaia DR1 space data. Assuming the sy…
