From Interstellar Clouds to Star-Forming Galaxies: Universal Processes?      2016   [Refereed]
We present high resolution molecular line observations of dusty AGN and starburst in nearby luminous infrared galaxies (LIRGs), VV 114 (band 3/4/7) and NGC 1614 (band 3/6/7/9), with ALMA. Multi-frequency imaging from 4.8 GHz to 691 GHz of NGC 1614...
Revolution in Astronomy with ALMA: The Third Year      Dec 2015   [Refereed]
We present observations of a protoplanetary disk around a Herbig Ae star HD 163296 obtained from the ALMA Science Verification data, as well as the Nobeyama 45 m and the ASTE 10 m single dish telescope observations. Double-peaked emission profiles...
Revolution in Astronomy with ALMA: The Third Year      Dec 2015   [Refereed]
We present high resolution (0".2 - 2."0) ALMA cycle 2 observations of the IR-bright mid-stage merger VV 114 (band 3), the minor merger NGC 1614 (band 3/6), and the early-stage merger NGC 3110 (band 3), which are supplemented with the cycle 0 obser...

We present the results of Atacama Large Millimeter/Submillimeter Array (ALMA)
108, 233, 352, and 691 GHz continuum observations and Very Large Array (VLA)
4.81 and 8.36 GHz observations of the nearby luminous merger remnant NGC 1614.

Compiling data from literature and the ALMA archive, we show enhanced
HCN(4-3)/HCOTex(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 in starburst (SB)...

Some natural proteins display recurrent structural patterns. Despite being
highly similar at the tertiary structure level, repetitions within a single
repeat protein can be extremely variable at the sequence level. We propose a
mathematical defini...

We present ALMA Cycle 1 observations of the central kpc region of the
luminous type-1 Seyfert galaxy NGC 7469 with unprecedented high resolution
(0.5Tex Tex 0.4Tex = 165 pc Tex 132 pc) at submillimeter wavelengths.
Utilizing the wide-ban...

   Aug 2015
We present the first simultaneous spectral energy distribution (SED) of M87
core at a scale of 0.4 arcsec (Tex) across the electromagnetic
spectrum. Two separate, quiescent, and active states are sampled that are
characterized by a...

   Jun 2015
We present an unprecedented measurement of the disc stability and local
instability scales in the luminous infrared Seyfert 1 host, NGC7469, based on
ALMA observations of dense gas tracers and with a synthesized beam of 165 x 132
pc. While we conf...
