The ALMA Survey of Gas Evolution of PROtoplanetary Disks (AGE-PRO). III. Dust and Gas Disk Properties in the Lupus Star-forming Region

open access: yesThe Astrophysical Journal
We present Band 6 and Band 7 observations of 10 Lupus disks around M3-K6 stars from the Atacama Large Millimeter/submillimeter Array survey of Gas Evolution in PROtoplanetary disks (AGE-PRO) Large Program. In addition to continuum emission in both bands,

Discovery of a Multiply Lensed Submillimeter Galaxy in Early HerMES Herschel/SPIRE Data [PDF]

open access: yes, 2011
We report the discovery of a bright (f(250 μm)>400 mJy), multiply lensed submillimeter galaxy HERMES J105751.1+573027 in Herschel/SPIRE Science Demonstration Phase data from the HerMES project.

A Simultaneous Stacking and Deblending Algorithm for Astronomical Images

open access: yes, 2010
Stacking analysis is a means of detecting faint sources using a priori position information to estimate an aggregate signal from individually undetected objects. Confusion severely limits the effectiveness of stacking in deep surveys with limited angular

exoALMA XXII: A Two-dimensional Atlas of Deviations from Keplerian Disks

open access: yesThe Astrophysical Journal Letters
Protoplanetary disks are the birthplaces of planetary systems, and deviations from Keplerian rotation imprinted in disk gas kinematics serve as key tracers of physical processes and the presence of protoplanets within disks.

Discovery of Radio Recombination Lines from Proplyds in the Orion Nebula Cluster

open access: yesThe Astrophysical Journal
We present new Atacama Large Millimeter/submillimeter Array observations that, for the first time, detect hydrogen and helium radio recombination lines from a protoplanetary disk.

Constraints on the Physical Origin of Large Cavities in Transition Disks from Multiwavelength Dust Continuum Emission

open access: yesThe Astrophysical Journal
The physical origin of the large cavities observed in transition disks is to date still unclear. Different physical mechanisms (e.g., a companion, dead zones, enhanced grain growth) produce disk cavities of different depth, and the expected spatial ...

Spitzer Imaging of Herschel-ATLAS Gravitationally Lensed Submillimeter Sources [PDF]

open access: yes, 2011
We present physical properties of two submillimeter selected gravitationally lensed sources, identified in the Herschel Astrophysical Terahertz Large Area Survey.

Submillimeter Astronomy from the South Pole (AST/RO) [PDF]

open access: yesProceedings of the International Astronomical Union, 2012
AbstractThe Antarctic Submillimeter Telescope and Remote Observatory (AST/RO), a 1.7 m diameter offset Gregorian telescope for astronomy and aeronomy studies at wavelengths between 200 and 2000 μm, saw first light in 1995 and operated until 2005. It was the first radio telescope to operate continuously throughout the winter on the Antarctic Plateau. It

The JCMT Transient Survey: Six Year Summary of 450/850 μm Protostellar Variability and Calibration Pipeline Version 2.0

open access: yesThe Astrophysical Journal
The James Clerk Maxwell Telescope (JCMT) Transient Survey has been monitoring eight Gould Belt low-mass star-forming regions since 2015 December and six somewhat more distant intermediate-mass star-forming regions since 2020 February with the ...

Submillimeter spectroscopy of interstellar hydrides [PDF]

open access: yes, 1995
We discuss airborne observations of rotational transitions of various hydride molecules in the interstellar medium, including H_2^(18)O and HCI. The detection of these transitions is now feasible with a new, sensitive submillimeter receiver which has ...
