ATHENA: A NEW CODE FOR ASTROPHYSICAL MHD
A new code for astrophysical magnetohydrodynamics (MHD) is described. The code has been designed to be easily extensible for use with static and adaptive mesh refinement. It combines higher order
Astrophysics Source Code Library
TLDR
The editors of the AsCL and members of its Advisory Committee were on hand at a demonstration table in the ADASS poster room to present the ASCL, accept code submissions, show how the ASLI is starting to be used by the astrophysics community, and take questions on and suggestions for improving the resource.
High-Velocity Clouds: Building Blocks of the Local Group
We suggest that the high-velocity clouds (HVCs) are large clouds, with typical diameters of 25 kpc, containing 3×107 M☉ of neutral gas and 3×108 M☉ of dark matter, falling onto the Local Group;
The Astropy Project: Building an Open-science Project and Status of the v2.0 Core Package
The Astropy Project supports and fosters the development of open-source and openly developed Python packages that provide commonly needed functionality to the astronomical community. A key element of
The Simultaneous Spectrum of Sagittarius A* from 20 Centimeters to 1 Millimeter and the Nature of the Millimeter Excess
We report results of a multiwavelength campaign to measure the simultaneous spectrum of the supermassive black hole candidate Sgr A* in the Galactic center from centimeter to millimeter wavelengths
The Spitzer c2d Survey Of Nearby Dense Cores. II. Discovery Of A Low-Luminosity Object In The "Evolved Starless Core" L1521F
We present Spitzer Space Telescope observations of the "evolved starless core" L1521F that reveal the presence of a very low luminosity object (L 5μm), but only in scattered light at shorter infrared
Definition of the Flexible Image Transport System (FITS)
The Flexible Image Transport System { FITS { has been in use in the astronomical community for over two decades. A newly updated version of the standard has recently been approved by the
THE ASTROPY PROJECT : BUILDING AN INCLUSIVE , OPEN-SCIENCE PROJECT AND STATUS OF THE V 2 . 0 CORE PACKAGE
The Astropy project supports and fosters the development of open-source and openly-developed Python packages that provide commonly-needed functionality to the astronomical community. A key element of
Secular Evolution via Bar-driven Gas Inflow: Results from BIMA SONG
We present an analysis of the molecular gas distributions in the 29 barred and 15 unbarred spirals in the BIMA CO (J = 1-0) Survey of Nearby Galaxies (SONG). For galaxies that are bright in CO, we
Kinematics of Spiral-Arm Streaming in M51
We use CO and Hα velocity fields to study the gas kinematics in the spiral arms and interarms of M51 (NGC 5194), and fit the 2D velocity field to estimate the radial and tangential velocity
