63. Eleonora Torresi - Cold molecular gas and nuclear activity in radio galaxies: Linking properties on macro and micro scales

12/06/2023, 15:30

Cross-population radio galaxies (FRII-LERG, i.e., powerful radio sources with an inefficient engine) are a powerful tool to investigate the long-standing relation between accretion and ejection. Indeed, they break the classical one-to-one correspondence between accretion mode and radio morphology by separating the effects of optical and radio classifications. To shed light on the nature of...

65. Elena Redaelli - The core population and kinematics of a massive clump: an ALMA view of AG14.49

12/06/2023, 15:31

High-mass stars dominate the kinematics and energetics of the interstellar medium, and yet their initial stages are poorly known. In fact, high-mass stars are born in crowded, dense, and distant environments (infrared dark clouds) that pose significant observational challenges. In this work, we use a combination of several ALMA datasets to investigate the properties of the high-mass clump...

66. Farideh S. Tabatabaei - Unveiling the interplay between magnetic fields and accretion in a young protocluster

12/06/2023, 15:32

The Pipe Nebula and Barnard 59 The Pipe Nebula is one of the closest known star-forming regions, with a distance of d = 163 pc (Dzib et al. 2018). The Pipe cloud has a very low rate of star formation. Indeed, only one active star-forming clump, Barnard 59 (B59), has been found in the cloud (Brooke et al. 2007; Forbrich et al. 2009, 2010). Alves et al. (2008) and Franco et al. ...

70. Vincenzo Galluzzi - A multi-frequency polarimetric study of the Radio Galaxy "Pictor A"

12/06/2023, 15:33

Pictor A is one of the brightest and most extended radio sources of the Southern Hemisphere. Its distinctive FRII morphology is characterized by two hotspot complexes, each at the edge of a diffuse and roundish lobe: the Western one, i.e. the brightest, shows a more standard morphology, dominated by a compact feature preceded by a filamentary structure orthogonal to the jet direction, while...

69. Fabrizio Gentile - Radio-Selected NIR-Dark galaxies: the ALMA view behind the dust

12/06/2023, 15:34

Since the first (sub)mm observations, it has been clear that the cosmic census of high-z galaxies based on deep optical/NIR surveys is far from complete. The ”darkest galaxies”, in which significant amounts of dust absorb the stellar emission, are in fact missed by these surveys, even though their contribution to the cosmic Star Formation Rate Density and to the evolution of massive galaxies...

62. Cleo Whitcombe - Millimetre-wave spectroscopy of pyrrole: a model for astrophysical searches

12/06/2023, 15:35

Pyrrole (c-C4H4NH) is a five-membered heterocyclic ring with C2v point group symmetry. The microwave and millimetre wave spectra of pyrrole and its isotopologues have been investigated since 1952, however, to improve the model’s accuracy, we propose the laboratory search within the 60-78 GHz region in which no experimental data is available at present. The free-jet absorption millimetre wave...

64. Wentao Song - Rotational spectroscopic study of cysteamine

12/06/2023, 15:36

Cysteamine (NH2CH2CH2SH) is a molecule that is potentially of interest to astrobiology, but it has not yet been detected in the interstellar medium. Its rotational spectrum was investigated in the 18-40 GHz frequency region and two conformers and their vibrational satellites were characterized [1], but the sparse frequency coverage prevents their accurate predictions in higher frequency...

67. Alice Nucara - The Rosetta-Stone project: a comparison between observations and simulations to investigate the star-formation mechanism in massive regions

12/06/2023, 15:37

In the context of star-formation the Rosetta-Stone project aims to investigate the star-forming mechanisms governing a sample of massive clumps. To reach our goal we focus on the properties of a sample of 13 sources at various evolutionary stages selected from the SQUALO project, an ALMA 1.3 mm survey. The physical properties of the fragments identified in these images such as their number,...

68. Andrea Maggio - Free jet millimeter wave torsion-rotation spectrum of a silicon containing molecule: dimethylsylane

12/06/2023, 15:38

In the interstellar and circumstellar medium, Silicon can be found in form of silicates in the core of dust grains surroaunding carbon stars; when the grains are destroyed it quickly reacts to form SiO and SiS. As today, among the 260 and more molecular species found in the interstellar medium, less than fifteen are silicon-based, so the research of molecules containing Silicon is crucial to...

73. Meriem Behiri - Discovering unexplored SHORES of the radio Universe

12/06/2023, 15:39

The Serendipitous H-ATLAS-field Observations of Radio Extragalactic Sorces (SHORES, PI: Massardi) is a 2GHz survey recently completed with ATCA for 30 fields (for a total coverage of 15deg2) centered on lensed galaxies in the H-ATLAS SGP region. The fields have been selected to be rich of ancillary data from mm to optical band. Our observations to a sensitivity <150ujy (down to 8ujy in our...

72. Alice Somigliana - A way to disentangle between viscous and MHD evolution in protoplanetary discs

12/06/2023, 15:40

The gaseous component of protoplanetary discs has traditionally been described as undergoing viscous accretion; this picture, however, is being challenged by the observational evidence of levels of turbulence in discs too low to account for the observed evolution. The alternative scenario of MHD disc winds is being explored as potentially able to reproduce the same observed evolutionary...
