New data announcement! The Swift+MaNGA (SwiM) VAC is a compilation of Swift & SDSS images w/MaNGA maps, transformed to have the same spatial & angular resolution/sampling. Find data here: https://t.co/IPEv37fAu8, and the submitted paper here: https://t.co/s3kQHrLIfW

Congratulations to the @eBOSSurvey Team on the final catalogs and cosmology results!

[Sloan Digital Sky Surveys @sdssurveys]

We’re very happy announce our mini data release DR16+, which contains the final eBOSS catalogs, two new MaNGA VACs (= value added catalogs) and one new old galaxy VAC (the NSA catalog). You can find all of them on https://t.co/Xma65m1l38. #DR16+

Screenshot from @Marvin_SDSS . Check out our data quality at 2.5 times the effective radius in this galaxy. The Halpha flux is 5x10^(-18) erg/s/cm^2 in that 0.5x0.5 square arcsec spaxel. And look at the asymmetry in the Halpha map!

Spectrophotometric calibration compared to photometry.

[MaStar @MaStar_library]

The spectrophotometric calibration for @MaStar_library spectra are getting close to rival calibration from photometry. Currently at 2.7% in r-i color and 3.9% in g-r color, or 29 and 42 millimags, respectively.

[MaStar @MaStar_library]

Trying to cover as wide a stellar parameter space as possible. Here is a comparison to the MILES library. We are still improving our coverage in current observations. Trying to do even better.

[MaStar @MaStar_library]

There are many ways to get the @MaStar_library data. You can search for stars and browse the spectra on the Science Archive Server: https://t.co/umaStk1fX2
or download the whole catalog and whole set of spectra from the direct download links.

#dr15 is now live!!! Go get the newest @sdssurveys data, including data from @MaStar_library . https://t.co/CK5zYqRRJP

[Sloan Digital Sky Surveys @sdssurveys]

The @MaNGASurvey data reduction pipeline is described on the website here: https://t.co/OZZnhEtViG, and also in Law et al. 2016: https://t.co/aEXjntromh #dr15

[Sloan Digital Sky Surveys @sdssurveys]

Big shout-out to the @Marvin_SDSS team: Brian Cherinka, José Sánchez-Gallego, Brett Andrews, Joel Brownstein and Maria Argudo-Fernández for developing, testing and documenting Marvin for #dr15!

[Sloan Digital Sky Surveys @sdssurveys]

This webpage also has instruction on how to install @Marvin_SDSS on your own laptop. Then get started with Marvin examples and tutorials available here: https://t.co/fM7xF20VtK and here: https://t.co/OWhEp30Tcf. No need to download any data! #dr15

[Sloan Digital Sky Surveys @sdssurveys]

We have a whole tutorial with video on-line to show you what else you can do with @Marvin_SDSS web: https://t.co/oDxEBW82Sm, have a look! #dr15

[Sloan Digital Sky Surveys @sdssurveys]

Change the maps to see emission line kinematics, or line indices. Or click in the galaxy image to see the spectra. Or click on 'galaxy properties' to see how this galaxy compares to the rest of the @MaNGASurvey sample #dr15

[Sloan Digital Sky Surveys @sdssurveys]

Want to see the galaxy featured in the #dr15 data release paper Aguado et al. 2018? Type 7443-12703 as plate or ID designation, and then toggle the red button Map/Spec View to get spectra and maps

[Sloan Digital Sky Surveys @sdssurveys]

Best way to explore @MaNGASurvey data? Ask @Marvin_SDSS, our brandnew visualisation and analysis webpage and tool. Let's get started with Marvin web: https://t.co/RqD49Wn9pB #dr15

[Sloan Digital Sky Surveys @sdssurveys]

While the @MaNGASurvey data analysis pipeline (DAP) is brandnew to the SDSS datareleases! Webpage with more info is here: https://t.co/MUWblHCLBu and we have two papers in prep, to appear on astro-ph soon #dr15

[MaStar @MaStar_library]

Here are some of the spectra in the @MaStar_library. Showing you the OBAFGKM main sequence stars in the left two columns, and a few yellow/red giant stars in the right column. See the variety of spectral types.

[Renbin Yan @yanrenbin]

@MaStar_library has been a large part of my life in the past few years, and will continue to be for the next few years. This is only the debut release of a large, comprehensive stellar spectral library. #dr15 @sdssurveys

[MaStar @MaStar_library]

Another H-R diagram for @MaStar_library using @ESAGaia bandpasses. We cover metal-poor stars and cool dwarf regime more extensively than previous efforts.
