FAST reveals new evidence for M94 as a merger
Ruilei Zhou, Ming Zhu, Yanbin Yang +4
We report the first high-sensitivity HI observation toward the spiral galaxy M94 with the Five-hundred-meter Aperture Spherical radio Telescope (FAST). From these observations, we…
The LOFAR view of giant, early-type galaxies: radio emission from active nuclei and star formation
A. Capetti, M. Brienza, B. Balmaverde +7
We study the properties and the origin of the radio emission in the most luminous early-type galaxies (ETGs) in the nearby Universe (MK<-25, recession velocity < 7,500 km/s) as see…
A 2-3 mm high-resolution molecular line survey towards the centre of the nearby spiral galaxy NGC 6946
Cosima Eibensteiner, Ashley T. Barnes, Frank Bigiel +30
The complex physical, kinematic, and chemical properties of galaxy centres make them interesting environments to examine with molecular line emission. We present new " (${\sim…
Extragalactic globular clusters with Euclid and other wide surveys
Ariane Lançon, S. Larsen, K. Voggel +14
Globular clusters play a role in many areas of astrophysics, ranging from stellar physics to cosmology. New ground-based optical surveys complemented by observations from space-bas…
Low star formation efficiency due to turbulent adiabatic compression in the Taffy bridge
B. Vollmer, J. Braine, B. Mazzilli-Ciraulo +1
The Taffy system (UGC 12914/15) consists of two massive spiral galaxies which had a head-on collision about 20 Myr ago. New sensitive, high-resolution CO(1-0) observations of the T…
The third realization of the International Celestial Reference Frame by very long baseline interferometry
P. Charlot, C. S. Jacobs, D. Gordon +17
A new realization of the International Celestial Reference Frame (ICRF) is presented based on the work achieved by a working group of the International Astronomical Union (IAU) man…
A study of extragalactic planetary nebulae populations based on spectroscopy. I. Data compilation and first findings
Gloria Delgado-Inglada, Jorge García-Rojas, Grazyna Stasińska +1
We compile published spectroscopic data and [O III] magnitudes of almost 500 extragalactic planetary nebulae (PNe) in 13 galaxies of various masses and morphological types. This is…
Detection of deuterated molecules, but not of lithium hydride, in the z=0.89 absorber toward PKS1830-211
S. Muller, E. Roueff, J. H. Black +8
Deuterium and lithium are light elements of high cosmological and astrophysical importance. In this work we report the first detection of deuterated molecules and a search for lith…
The 1.28 GHz MeerKAT DEEP2 Image
T. Mauch, W. D. Cotton, J. J. Condon +101
We present the confusion-limited 1.28 GHz MeerKAT DEEP2 image covering one FWHM primary beam area with FWHM resolution and Jy/beam rms nois…
Diffuse ionized gas and its effects on nebular metallicity estimates of star-forming galaxies
N. Vale Asari, G. S. Couto, R. Cid Fernandes +5
We investigate the impact of the diffuse ionized gas (DIG) on abundance determinations in star-forming (SF) galaxies. The DIG is characterised using the H equivalent width ($W_{…
The host galaxies of luminous type 2 AGN at 0.3-0.4
J. J. Urbano-Mayorgas, M. Villar Martín, F. Buitrago +7
We study the morphological and structural properties of the host galaxies associated with 57 optically-selected luminous type 2 AGN at 0.3-0.4: 16 high-luminosity Seyfert 2…
Spectroscopic characterization of the protocluster of galaxies around 7C 1756+6520 at z ~ 1.4
V. Casasola, L. Magrini, F. Combes +6
The aim of this paper is the spectroscopic study of 13 galaxies belonging to the field of the protocluster associated with the radio galaxy (RG) 7C 1756+6520 at z = 1.4156. In part…
Characterising the Circum-Galactic Medium of Damped Lyman- Absorbing Galaxies
Ramona Augustin, Celine Peroux, Palle Moller +8
Gas flows in and out of galaxies through their circumgalactic medium (CGM) are poorly constrained and direct observations of this faint, diffuse medium remain challenging. We use a…
Spatially Resolved Metal Gas Clouds
Celine Peroux, Hadi Rahmani, Fabrizio Arrigoni Battaia +1
We now have mounting evidences that the circumgalactic medium (CGM) of galaxies is polluted with metals processed through stars. The fate of these metals is however still an open q…
Detection of CH+, SH+, and their 13C- and 34S- isotopologues toward PKS1830-211
S. Muller, H. S. P. M"uller, J. H. Black +13
The z=0.89 molecular absorber toward PKS1830-211 provides us with the opportunity to probe the chemical and physical properties of the interstellar medium in the disk of a galaxy a…
Chemical abundances of giant stars in NGC 5053 and NGC 5634, two globular clusters associated with the Sagittarius dwarf Spheroidal galaxy?
L. Sbordone, L. Monaco, C. Moni Bidin +8
The tidal disruption of the Sagittarius dwarf Spheroidal galaxy (Sgr dSph) is producing the most prominent substructure in the Milky Way (MW) halo, the Sagittarius Stream. Aside fr…
On the cosmic evolution of the specific star formation rate
M. D. Lehnert, W. van Driel, L. Le Tiran +2
The apparent correlation between the specific star formation rate (sSFR) and total stellar mass (M_star) of galaxies is a fundamental relationship indicating how they formed their…
Ram pressure stripping of the multiphase ISM in the Virgo cluster spiral galaxy NGC 4438
B. Vollmer, M. Soida, A. Chung +4
Ram pressure stripping of the multiphase ISM is studied in the perturbed Virgo cluster spiral galaxy NGC 4438. This galaxy underwent a tidal interaction ~100 Myr ago and is now str…
