We present Atacama Large Millimeter/submillimeter Array (ALMA) observations from the 2014 Long Baseline Campaign in dust continuum and spectral line emission HL Tau region. The images at wavelengths of 2.9, 1.3, 0.87 mm have unprecedented angular resolutions 0 075 (10 AU) to 025 (3.5 AU), revealing an astonishing level detail circumstellar disk surrounding young solar analog Tau, with a pattern bright dark rings observed all wavelengths. By fitting ellipses most distinct rings, we measure...
A major goal of the Atacama Large Millimeter/submillimeter Array (ALMA) is to make accurate images with resolutions tens milliarcseconds, which at submillimeter (submm) wavelengths requires baselines up ~15 km. To develop and test this capability, a Long Baseline Campaign (LBC) was carried out from September late November 2014, culminating in end-to-end observations, calibrations, imaging selected Science Verification (SV) targets. This paper presents an overview campaign its main results,...
We present the first simultaneous spectral energy distribution (SED) of M87 core at a scale 0.4 arcsec ( ∼ 32 pc) across electromagnetic spectrum. Two separate, quiescent, and active states are sampled that characterized by similar featureless SED power-law form, thus remarkably different from canonical galactic nuclei or radiatively inefficient accretion source. show emission jet gives an excellent representation covering ten orders magnitude in frequency for both quiescent phases. The...
The high spatial and line sensitivity of ALMA opens the possibility resolving emission from molecules in circumstellar disks. With an understanding physical conditions under which have abundance, they can be used as direct tracers distinct regions. In particular, DCO+ is expected to enhanced abundance within a few Kelvin CO freezeout temperature 19 K, making it useful probe cold disk midplane. We compare observations HD 163296 grid models. vary upper- lower-limit temperatures region present...

ABSTRACT Compiling data from literature and the Atacama Large Millimeter/submillimeter Array archive, we show enhanced HCN(4–3)/HCO + (4–3) and/or HCN(4–3)/CS(7–6) integrated intensity ratios in circumnuclear molecular gas around active galactic nuclei (AGNs) compared to those starburst (SB) galaxies (submillimeter HCN enhancement). The number of sample is significantly increased our previous work. We expect that this feature could potentially be an extinction-free energy diagnostic tool...
