Allen, Deborah Baines, Sarah Emery Bunn, +Chenzou Cui, August Muench, Mark Taylor, & Ivan Zolotukhin. + +** The International Virtual Observatory Alliance (IVOA) was formed in June 2002 +with a mission to facilitate the international coordination and collaboration +necessary for the development and deployment of the tools, systems and +organizational structures necessary to enable the international utilization of +astronomical archives as an integrated and interoperating virtual observatory. +The IVOA now comprises 20 VO programs from Argentina, Armenia, Australia, +Brazil, Canada, Chile, China, Europe, France, Germany, Hungary, India, Italy, +Japan, Russia, South Africa, Spain, Ukraine, the United Kingdom, and the United +States and an inter-governmental organization (ESA). Membership is open to other +national and international programs according to the +[IVOA Guidelines for Participation](http://ivoa.net/Documents/latest/IVOAParticipation.html). +You can read more about the IVOA and what we do at .** + +### What is the VO? + +The Virtual Observatory (VO) aims to provide a research environment that will +open up new possibilities for scientific research based on data discovery, +efficient data access, and interoperability. The vision is of global astronomy +archives connected via the VO to form a multiwavelength digital sky that can be +searched, visualized, and analyzed in new and innovative ways. VO projects +worldwide working toward this vision are already providing science capabilities +with new tools and services. This newsletter, aimed at astronomers, highlights +VO tools and technologies for doing astronomy research, recent papers, and +upcoming events. + +--- + +# IVOA news + +{{< side-image image="ChiVO.png" position="left" >}} + +### Chilean Virtual Observatory (ChiVO) joins the IVOA + +The Chilean VO, which is supported by five Chilean universities, ALMA, and the +REUNA research consortium, was welcomed into the IVOA at the September 2013 IVOA +meeting. ChiVO will focus on building the tools and technology infrastructure +necessary for Chilean researchers to take advantage of the terabytes of data +that will be produced by ALMA. More information can be found at +. + +{{}} + +{{< side-image image="ProcessDiagram_crop2.png" position="right" >}} + +### Moving forward with Data Standards + +The past six months have seen the recommendation of three new data standards. These include a [Photometry Data Model](http://ivoa.net/documents/PHOTDM/index.html) for describing photometric systems, and two specifications for data access services ([Data Access Layer Interface](http://ivoa.net/documents/DALI/index.html), [Describing Simple Data Access Services](http://ivoa.net/documents/SimpleDALRegExt/index.html)). The VOTable standard, which is an XML standard for the interchange of tables of data and metadata, moved to [version 1.3](http://www.ivoa.net/documents/VOTable/). + +{{}} + +--- + +# VO applications and implementation highlights + +{{< side-image image="TAO_illust.png" thumbnail="TAO_illust.png" position="right" >}} + +### Theoretical Astrophysical Observatory (TAO) + +The Australian VO is happy to announce the launch of the TAO, which houses +queryable data from multiple popular cosmological simulations and galaxy +formation models. Results can be funnelled through higher-level modules to build +custom mock galaxy catalogues and images. TAO is accessible from anywhere you +can access the internet. TAO is part of the All-Sky Virtual Observatory (ASVO) +and is funded and supported by Astronomy Australia Limited, the National +eResearch Collaboration Tools and Resources (NeCTAR), and Swinburne University +of Technology. + +**More Information:** + +{{}} + +{{< side-image image="voclient.png" thumbnail="voclient.png" position="left" >}} + +### VO Client Release - Access the VO from your desktop + +The US Virtual Astronomical Observatory (VAO) has released VOClient - a software +package that enables direct access to services in the VO from a Unix terminal or +scripting environment. The VOClient command-line tools allow you to discover +archives and catalogs through queries to the VAO Registry, search-for and +download images, spectra, and catalogs, and interoperate with other +VO-compatible tools. These tools can be used to create customized access to VO +services, new VO tools or enhancements to existing software by adding VO +capabilities. + +**More Information:** + +{{}} + +{{< side-image image="vtp.png" thumbnail="vtp.png" position="right" >}} + +### Comet, a Python implementation of the VOEvent Transport Protocol + +VOEvent is the IVOA system for describing transient celestial events. Details of +transients detected by many projects, including Fermi, Swift, and the Catalina +Sky Survey, are currently made available as VOEvents, and it has been selected +as the standard alert format by future facilities such as LSST and SKA. Comet is +an implementation of the VOEvent Transport Protocol, which makes the fast and +reliable distribution of VOEvents to the community possible. Comet enables you +to subscribe to real-time streams of ongoing events, to use filters to select +only events relevant to your science case and to publish your own events to the +global VOEvent backbone.

New +features include sky axes, the ability to plot vectors, ellipses, contours and +analytic functions, hybrid scatter/density plots, improved 3d navigation, better +interactive response, LaTeX labelling of axes, more configurability, and better +performance for large (multi-million-row) tables. As well as visualisation, +TOPCAT continues to provide a wide range of other analysis capabilities for +tabular data including VO access, crossmatching and row selections. + +**More Information:** + +{{}} + + +{{< side-image image="ssap_vamdc.jpg" thumbnail="ssap_vamdc.jpg" position="right" >}} + +### CASSIS: Version 3.6.1 released + +The latest release of CASSIS (Centre d'Analyse Scientifique de Spectres +Instrumentaux et Synthétiques), version 3.6.1, is available for download since +March 4, 2014. CASSIS provides tools to visualize and analyze spectra, in +particular to perform line identification. A number of changes have been and are +being implemented to make CASSIS VO-compatible. CASSIS now includes a Simple +Spectral Access (SSA) module and also allows the user to interrogate the VAMDC +online database (http://www.vamdc.eu/access-data/portal), rather than a local +database. Both of these features are illustrated in the accompanying figure: the +top panel shows a SSA query on Orion with the responses from different services +being displayed in different tabs, while the bottom panel shows the display of +the selected ISO-LWS spectrum, overlaid with all CO transitions found in the +VAMDC/CDMS database and potentially present in the spectrum (green lines); +clicking on any of these lines displays the associated spectroscopic parameters. + +**More Information:** + +{{}} + +{{< side-image image="ETC-Logo-125.png" thumbnail="ETC-Logo-125.png" position="left" >}} + +### ETC-42 + +ETC-42 is a Generic Exposure Time Calculator developed by CeSAM/LAM. Unlike +usual existing ETCs, it can calculate the Signal to Noise Ratio (SNR) for any +site and instrumentation type and perform simulations for a wide range of +existing or future telescopes. It can simulate objects using theoretical +spectral distributions (black bodies, flat energy flux, etc) or with user +defined (or imported via SAMP) spectra. Simulation results can be saved, +exported or broadcast in VOTable format. A plugin framework is also available +for pre and post process of simulations.

We obtain data of ~10, 000 Sloan +Digital Sky Survey AGNs in which their virial masses with a supermassive black +hole (SMBH) were estimated. The UKIDSS galaxy samples around the AGNs were +obtained using the virtual observatory. The scale length of AGN-galaxy +cross-correlation for all of the samples is measured to be r_0= +5.8^{+0.8}_{-0.6}\,h^{-1}\,Mpc (for the fixed slope parameter γ = 1.8). We also +derived a dependence of r0 on the BH mass, MBH, and found an indication of an +increasing trend of r0 at MBH > 108 M⊙. It is suggested that the growth of SMBHs +is mainly driven by interactions with the surrounding environment for MBH > 108 +M⊙. On the other hand, at MBH <~ 108 M⊙, we did not find the BH mass dependence. +This would imply that for less massive BHs, the mass growth process can be +different from that for massive BHs. + +### Refereed Publications + +* [Astropy: A community Python package for astronomy](http://adsabs.harvard.edu/abs/2013A%26A...558A..33A) + _Astropy Collaboration + Astronomy & Astrophysics, Volume 558, id.A33, 9 pp. (2013)._ + +* [Characterization of the gaseous companion κ Andromedae b.
