Today is a big day for us: it's DATA RELEASE DAY!!! And to celebrate our nineteenth data release, we have not one, but two papers for you to read all about our data: we have a DR19 paper (arxiv.org/abs/2507.07093) and an SDSS-V Overview paper (arxiv.org/abs/2507.06989) #DR19

We are releasing a total of ~380,000 BOSS spectra in DR19 for ~120,000 distinct objects primarily targeted for spectroscopy by BHM, an order of magnitude expansion vs. DR18. sdss.org/dr19/bhm/data/… sdss.org/dr19/bhm/data/…

We have a data release! Check out sdss.org/dr19 for all the data that just became publicly available with our 19th data release #DR19

We are releasing several new Jupyter Notebook style tutorials to help you use the new SDSS-V DR19 data: sdss.org/dr19/bhm/tutor… github.com/sdss/dr19_tuto…

SDSS-V Black Hole Mapper is releasing the “Spectral Identification of eROSITA Sources DR19: Optical and X-ray properties” sdss.org/dr19/data_acce…

SDSS-V Black Hole Mapper is releasing “The Sloan Digital Sky Survey DR19 quasar spectral property catalog” sdss.org/dr19/data_acce…

Black Hole Mapper had already released a few spectra in DR18, but they are going all out for DR19, with lots of galaxy and quasar spectra #DR19

All Black Hole Mapper science programs are available here, sdss.org/dr19/bhm/progr…, and they include time domain programs such AQMES (All-Quasar Multi-Epoch Spectroscopy and reverberation mapping, X-ray follow-up programs.

Black Hole Mapper also has a range of tutorials available to get you started working on the data: sdss.org/dr19/tutorials… #DR19
