All @blackholemapper.bsky.social science programs are available here, www.sdss.org/dr19/bhm/pro..., and they include time domain programs such AQMES (All-Quasar Multi-Epoch Spectroscopy and reverberation mapping, X-ray follow-up programs.

@blackholemapper.bsky.social had already released a few spectra in DR18, but they are going all out for DR19, with lots of galaxy and quasar spectra #DR19

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

Yesterday we released our nineteenth data release into the wild: www.sdss.org/dr19, let’s now take a closer look on what is in this data release. #DR19

First we have a tutorial around some basic themes relating to @blackholemapper.bsky.social . This introduces quasar spectra and redshift before moving in to time domain astronomy and looking at spectroscopic variability. You can find it here www.sdss.org/dr19/tutoria... 2/4

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

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

We are releasing several new Jupyter Notebook style tutorials to help you use the new SDSS-V DR19 data: www.sdss.org/dr19/bhm/tut... github.com/sdss/dr19_tu...

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 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. www.sdss.org/dr19/bhm/dat... www.sdss.org/dr19/bhm/dat...

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

Today is our first BHM Science Paper Day! The first science results to be published using BHM data were those of Zeltyn et al. (2022). This paper reports the discovery of a "changing-look quasar" using SDSS-V monitoring. The paper can be found here: arxiv.org/abs/2210.07258 1/

Let’s start getting to know some of the science results that have come from the Black Hole Mapper program so far! For the next few months, we will have a weekly “BHM results” post, each featuring a science journal article that has been published using Black Hole Mapper data.

A few of our Black Hole Mapper team members are representing at the “Multi-wavelength AGN Structure and Cosmological Applications” conference in Nice! We’re learning about all things AGN and enjoying copious amounts of French pastries. Here we are at Observatoire de la Côte d’Azur!

Hello, BlueSky! We are the Black Hole Mapper, a part of the SDSS-V survey aimed at exploring quasars across the Universe. We’ve finally made it over here and are happy to join the astronomy community here!

Huge congratulations to the Local Volume Mapper team, who passed Operational Readiness Review today! Lots of commissioning data from the IFUs, but now ready to official embark on their mission. Here's to the 4 little 🔭's that can!
