Telescope simulator We use the IRAM GILDAS simulator [11,12] to convolve to ALMA angular resolution. Aims. "In the future, the high sensitivity and angular resolution of the full ALMA array will allow us to make detailed studies of water in a wide range of objects including forming and evolved stars, the interstellar medium and regions close to supermassive black holes." A degree (angular degree, unit of angle corresponding to 1/360 of a full circle which is 1/90 of a right angle) is divided into 60 arcminutes (arcmin, minute of arc, or in context, minute or min), which, in . C alone (∼2′′ at 100GHz, ∼0.9′′ at 230GHz) is also well suited for snapshot and size measurements, and for de-tection experiments at low source declination. However, observations at very high radio frequencies with good angular resolution are still very scarce in the literature. astrophysics 13%. By performing ALMA simulations with different array configurations and exposure times, we conclude that 20-40 per cent of the total [C ii] flux might be missed when the angular resolution is comparable to the size of the emitting region, even when the level of significance of the line is ∼5-10σ. Like all synthesis arrays, the VLA is sensitive only to structures on a range of angular scales between the diffraction limit (the smallest angular scale detectable) and a "Largest Angular Scale" (which depends on the fringe spacing formed by the shortest .

First observation: That growth looks like some kind of deconvolution. NGC 1087 is a spiral galaxy located approximately 80 million light-years from Earth in the constellation of Cetus. Eight filaments are found converging to the central hub and extending for about 0.1 pc. Combined with precursor data, the PHANGS-ALMA sample provides fully-sampled data for 74 galaxies, combining ALMA's 12-m, 7-m, and total power arrays. ALMA angular resolution allowed us to map scales as small as ˘700 pc. Second: The better you can approximate it with fast tools, the faster you can simulate (in principle) the departures or errors in the approximation. For a fixed host galaxy mass model, the improvement in ALMA angular resolution (from resolving by a factor of ~2 to a factor of ~10) results in a relatively modest improvement in precision on .

This option may increase ALMA angular resolution by a factor of 10. However, both the spectroscopic confirmation of photometrically-selected galaxies at this epoch and the characterization of their early dynamical state has been hindered by the lack of bright, accessible lines to probe the velocity structure of their interstellar medium.
