The distribution of MaNGA information incorporates detailed maps of thousands of nearby galaxies

The latest news release from Sloan Digital Sky Survey (SDSS) includes ideas that can be viewed. Demonstrates the structure and design of nearly 5,000 galaxy nearby that was inspected in the three years of a Mapage Nearby Galaxies program at Observatory Point Apache (MaNGA).

MaNGA will use a method called "solvent spectroscopy" to monitor galaxies in much more precise than previous studies. Spectroscopy is a powerful tool for screwdrivers, and provides a wealth of information by clicking on it. measure the light that is given at different panels. In the end of time, usually searching for directories of only one spectrum for each galaxy, but an open-ended correction (known as a complete global scenes) which receives hundreds of separate spectraters to & # 39; covering each place inside the galaxy.

"Speroscopy has been resolved to provide us with the chance to test and involve galaxy and the movements of its stars and gas," said Mavin, lead researcher Kevin Bundy, Related Investigation at UC watchstops and astronomy professor and astrophysics at UC Santa Cruz.

"People have made decent spirals for individual galleries, but we never wanted thousands of diseases, so MaNGA gives us the statistical ability to deal with many of the questions important, "said Bundy.

The aim of MaNGA is to understand today's galax "biography" today, from its first birth and convention, through the continued growth through star-star creation and unions, until they die from & # 39; suffer by creating stars at the end of time. U.S. Santa Cruz, Bundy and his students, for example, have found evidence in MaNGA data for a stream of hot gas in "dead" galaxies, which supports the view that powerful winds can th & # 39; moved from a black hole galaxy dropping down the creation of a postcard The Post The Bundy team also explores how galaxies have been collected over time by; explore the movements of their stars and gas and by examining the chemical names of the stars in different parts of galaxies.

The Marvin website provides an easy access to wealth of information about each galaxy in the MaNGA survey, and including maps of key features such as star creation, temporary movement, distribution lines, and a number of other buildings that are important to rhetoric.

One of three programs in the fourth phase of SDSS, MaNGA will analyze a representative sample of around 10,000 galax nearby. Bundy said the survey is more than half a mile to that goal and on its way to reach by 2020. Data from 4,621 galaxy are now available publicly as part of the 15 SDSS information distribution (the third data copy for SDSS-IV).

"This data distribution is a huge milestone for us," said Bundy. "The largest survey in the MaNGA is already the largest survey, and this distribution includes the data and the analyzed tools that the project has developed. "

A new powerful interconnection called Marvin gives access to maNGA data and gala data based on analysis of the data. Marvin includes a wide range of tools for research, entry, and & # 39; show the data. The Marvin website offers easy access to the richness of information about each galaxy, and # 39; including maps of key features such as star creation, temporary movement, distribution lines, and a number of other buildings that are important to rhetoric. Kyle Westfall, a project scientist at the UC Theater, was the development of a pipeline development guide that created the maps and other data products that are now open to the public for his / her. first time.

Another important part of this data release is a Stellar MaNGA Library with spectacles of over 3,000 stars in our Milky Way. When it's finished, it will contain 5,000 to 6,000 stars. The astronomers' researchers can use these stars to try to reconstruct galaxy screensaver and thus show that there is a special galaxy variety of different types of star.

The MaNGA survey will receive a spectrum across the front of the galaxy target. Using customized fiber bundle bundles.

"The MaNGA Library Slolar Library is the largest of ever-starred star, with a spectrum from the only instruments used for galaxies, so it is a very powerful device to understand the nature of the numbers The biggest in these galaxies, "said Bundy.

MaNGA Renbin Yan of the University of Kentucky examined Stellar's Library.

The MaNGA survey will use the two BOSS detection at the 2.5-meter Sloan Foundation Telesgop at Apache Point Theater in New Mexico in a new way. By designing "relevant range units", each made of tough trees of flexible teeth, spectra has a chance to measure at many points in the same galaxy. The MaNGA spectra transmits continuous broadcasting from sunscreen to near near infrastructure.
