“…The results suggest that J0258+2030 (A3 1 ), J0253+1805 (A9 1 ), and J0257+1847 (A9 2 ) can have SFRs of 3.6 × 10 3 M ⊙ yr −1 , 3.3 × 10 4 M ⊙ yr −1 , and 2.9 × 10 2 M ⊙ yr −1 , respectively. The SFRs are similar to those studied in 16 radio galaxies with AzTEC counterparts in the far-IR and a gray-body emission template with an emissivity index, β, and a dust temperature, T d (Humphrey et al 2011).…”

We present 1.1 mm observations of the dust continuum emission from the MBM12 highlatitude molecular cloud observed with the Astronomical Thermal Emission Camera (AzTEC) mounted on the James Clerk Maxwell Telescope on Mauna Kea, Hawaii. We surveyed a 6.34 deg 2 centered on MBM12, making this the largest area that has ever been surveyed in this region with submillimeter and millimeter telescopes. Eight secure individual sources were detected with a signal-to-noise ratio of over 4.4. These eight AzTEC sources can be considered to be real astronomical objects compared to the other candidates based on calculations of the false detection rate. The distribution of the detected 1.1 mm sources or compact 1.1 mm peaks is spatially anti-correlated with that of the 100 µm emission and the 12 CO emission. We detected the 1.1 mm dust continuum emitting sources associated with two classical T Tauri stars, LkHα262 and LkHα264. Observations of spectral energy distributions (SEDs) indicate that LkHα262 is likely to be Class II (pre-main-sequence star), but there are also indications that it could be a late Class I (protostar). A flared disk and a bipolar cavity in the models of Class I sources lead to more complicated SEDs. From the present AzTEC observations of the MBM12 region, it appears that other sources detected with AzTEC are likely to be extragalactic and located behind MBM12. Some of these have radio counterparts and their star formation rates are derived from a fit of the SEDs to the photometric evolution of galaxies in which the effects of a dusty interstellar medium have been included.

“…Here we compare neutral and ionized gas kinematics in the starburst galaxy PKS 0529-549 at z 2.6, combining new [C I] (2 − 1) data from ALMA with IFS data from SINFONI (Nesvadba et al 2017). PKS 0529-549 is a well-studied radio galaxy with an exquisite set of ancillary data: optical spectroscopy, ground-based NIR imaging, and radio polarimetry (Broderick et al 2007), Spitzer/IRAC imaging (De Breuck et al 2010), and 1.1 mm data from AzTEC (Humphrey et al 2011). PKS 0529-549 hosts a Type-II AGN and shows two radio lobes.…”

We present a multiwavelength study of the AGN-host starburst galaxy PKS 0529-549 at z 2.6. We use (1) new ALMA observations of the dust continuum and of the [C I] 370 µm line, tracing molecular gas, (2) SINFONI spectroscopy of the [O III] 5007Å line, tracing ionized gas, and (3) ATCA radio continuum images, tracing synchrotron emission. Both [C I] and [O III] show regular velocity gradients, but their systemic velocities and position angles differ by ∼300 km s −1 and ∼30 • , respectively. The [C I]is consistent with a rotating disc, aligned with the dust and stellar continuum, while the [O III] likely traces an outflow, aligned with two AGN-driven radio lobes. We model the [C I] cube using 3D disc models, which give best-fit rotation velocities V rot 310 km s −1 and velocity dispersions σ V 30 km s −1 . Hence, the [C I] disc has V rot /σ V 10 and is not particularly turbulent, similar to local galaxy discs. The dynamical mass (∼10 11 M ) is comparable to the baryonic mass within the errors. This suggests that baryons dominate the inner galaxy dynamics, similar to massive galaxies at z 0. Remarkably, PKS 0529-549 lies on the local baryonic Tully-Fisher relation, indicating that at least some massive galaxies are already in place and kinematically relaxed at z 2.6. This work highlights the potential of the [C I] line to trace galaxy dynamics at high z, as well as the importance of multiwavelength data to interpret gas kinematics.

“…High angular resolution W-band measurements open at a number of possibilities of scientific cases, including galaxies spectral energy distribution measurement and their continuum observation [1], AGN and radio galaxies [2], detection of circumstellar disks [3], dense core in giant molecular gas investigation [4], synchrotron non thermal jet and hot spot [5], intraclusters filaments, cosmic web, and other S-Z related observation [6,7]; and even more, by correlating with other experiment.…”

Millimetric Sardinia radio Telescope Receiver based on Array of Lumped elements kids

MISTRAL is a millimetric camera working in the W-band (78–103 GHz) which will take data from the Sardinia Radio Telescope, the Italian 64-m radio telescope located 50 km form Cagliari, at 600m above the sea level, in Sardinia. It is being built as a facility instrument by the Sapienza University for INAF, that manages the radio telescope, under a PON contract. It will consist of a compact cryostat hosting the re–imaging optics, cooled at 4K, and a 408–pixel array of photon–noise limited lumped element kinetic inductance detectors fabricated at CNR-IFN and cooled at a base temperature lower than 300mK. MISTRAL will be able to investigate a long list of scientific targets spanning from extragalactic astrophysics to solar system science, with high angular resolution (~ 12 arcsec), including Sunyaev Zel’dovich effect measurements and the study of the Cosmic Web.
