Cieza, Sebastián Pérez, Valentin Christiaens, Jonathan P. Williams, Greta Guidi, Hector Cánovas, Simon Casassus, Antonio Hales, David A. Principe, Dary Ruíz-Rodríguez, Antonia Fernandez-Figueroa Abstract: We present Adaptive Optics (AO) near infrared (NIR) observations using VLT/NACO and Keck/NIRC2 of ODISEA targets. ODISEA is an ALMA survey of the entire population of circumstellar discs in the Ophiuchus molecular cloud. From the whole sample of ODISEA we select all the discs that are not already observed in the NIR with AO and that are observable with NACO. we detect 20 new binary systems and one triple system. 9 of them are in the sub-stellar regime (30-50MJup). Discs in multiple systems reach a maximum total dust mass of  50M, while discs in single stars can reach a dust mass of 200 M. Discs with masses above 10 M are found only around binaries with projected separations larger than  110 au. The maximum disc size is also larger around single star than binaries. MNRAS CH

Spilker, J. D. Vieira, G. Wang, A. Weiss Abstract We detect optical/IR counterparts for only nine of the 14 submillimetre galaxies (SMGs) previously identified by ALMA in the core of SPT2349-56. In addition, we detect four z∼4 Lyman-break galaxies (LBGs) in the 30 arcsec diameter region surrounding this proto-cluster core. Three of the four LBGs are new systems, while one appears to be a counterpar of one of the nine observed SMGs. SPT2349-56 therefore represents a truly dust-obscured phase of a massive cluster core under formation. NA

ALMA high spatial resolution (~ 7 au) images of the continuum at 1.1 mm and the HCN 3-2 line resolve different gas components towards GV Tau N, a gaseous disc with R~25 au, an ionized jet, and one (or two) molecular outflows. The asymmetric morphology of the gaseous disc shows that it has been eroded by the jet. we propose that the water emission

Harada, S. Takano, T. Nakajima, S. Martin, M. Krips, P. P. van der Werf, S. Aalto, A. Usero, K. Kohno Abstract: We present results from (ALMA) observations of CS from the nearby galaxy NGC 1068 (∼14 Mpc). This Seyfert 2 barred galaxy possesses a circumnuclear disc (CND, r∼200 pc) and a starburst ring (SB ring, r∼1.3 kpc). These high-resolution maps (∼0.5", ∼35 pc) allow us to analyse specifics. The temperature in the CND increases from east to west, and is also overall greater than found in the SB ring. These modelling methods indicate the requirement for multi-phase gas components in order to fit the observed emission over the galaxy. MNRAS Eu
