Identifying the first generation of radio powerful AGN in the Universe with the SKA
Jose Afonso, Jordi Casanellas, Isabella Prandoni +4
One of the most challenging and exciting subjects in modern astrophysics is that of galaxy formation at the epoch of reionisation. The SKA, with its revolutionary capabilities in t…
The physics of the radio emission in the quiet side of the AGN population with the SKA
M. Orienti, F. D'Ammando, M. Giroletti +2
Despite targets of many multiwavelength campaigns, the main physical processes at work in AGN are still under debate. In particular the origin of the radio emission and the mechani…
Molecular gas and nuclear activity in early-type galaxies: any link with radio-loudness?
Ranieri D. Baldi, Marcello Giroletti, Alessandro Capetti +4
Aims. We want to study the amount of molecular gas in a sample of nearby early-type galaxies (ETGs) which host low-luminosity Active Galactic Nuclei (AGN). We look for possible dif…

The nuclear starburst in the nearby galaxy M82 provides an excellent laboratory for understanding the physics of star formation. This galaxy has been extensively observed in the pa…
Discovery of Carbon Radio Recombination Lines in M82
Leah K. Morabito, J. B. R. Oonk, Francisco Salgado +30
Carbon radio recombination lines (RRLs) at low frequencies (<=500 MHz) trace the cold, diffuse phase of the interstellar medium, which is otherwise difficult to observe. We present…
LOFAR low-band antenna observations of the 3C295 and Bootes fields: source counts and ultra-steep spectrum sources
R. J. van Weeren, W. L. Williams, C. Tasse +98
We present LOFAR Low Band observations of the Bootes and 3C295 fields. Our images made at 34, 46, and 62 MHz reach noise levels of 12, 8, and 5 mJy beam, making them the dee…
Tentative Detection of the Nitrosylium Ion in Space
J. Cernicharo, S. Bailleux, E. Alekseev +8
We report the tentative detection in space of the nitrosylium ion, NO. The observations were performed towards the cold dense core Barnard 1-b. The identification of the NO…
The nature of the low-frequency emission of M51: First observations of a nearby galaxy with LOFAR
D. D. Mulcahy, A. Horneffer, R. Beck +25
The grand-design spiral galaxy M51 was observed with the LOFAR High Frequency Antennas (HBA) and imaged in total intensity and polarisation. This observation covered the frequencie…
Molecular line emission in NGC1068 imaged with ALMA: II. The chemistry of the dense molecular gas
S. Viti, S. García-Burillo, A. Fuente +19
We present a detailed analysis of ALMA Bands 7 and 9 data of CO, HCO+, HCN and CS, augmented with Plateau de Bure Interferometer (PdBI) data of the ~ 200 pc circumnuclear disk (CND…
The VLA-COSMOS Survey: V. 324 MHz continuum observations
Vernesa Smolcic, Paolo Ciliegi, Vibor Jelic +11
We present 90 cm VLA imaging of the COSMOS field, comprising a circular area of 3.14 square degrees at 8.0"x6.0" angular resolution with an average rms of 0.5 mJy/beam. The extract…
ATLASGAL-selected massive clumps in the inner Galaxy: I. CO depletion and isotopic ratios
A. Giannetti, F. Wyrowski, J. Brand +8
In the low-mass regime, it is found that the gas-phase abundances of C-bearing molecules in cold starless cores rapidly decrease with increasing density, as the molecules form mant…
Investigating the radio-loud phase of broad absorption line quasars
G. Bruni, J. I. González-Serrano, M. Pedani +5
Broad absorption lines (BALs) are present in the spectra of ~20% of quasars (QSOs); this indicates fast outflows (up to 0.2c) that intercept the observer's line of sight. These QSO…
Local Group dSph radio survey with ATCA (II): Non-thermal diffuse emission
M. Regis, L. Richter, S. Colafrancesco +3
Our closest neighbours, the Local Group dwarf spheroidal (dSph) galaxies, are extremely quiescent and dim objects, where thermal and non-thermal diffuse emissions lack, so far, of…
Local Group dSph radio survey with ATCA (I): Observations and background sources
M. Regis, L. Richter, S. Colafrancesco +4
Dwarf spheroidal (dSph) galaxies are key objects in near-field cosmology, especially in connection to the study of galaxy formation and evolution at small scales. In addition, dSph…
