Constraining the Mass of a Hypothetical Secondary Black Hole in M87 with the NANOGrav 15-Year Data Set
Galaxy mergers, each hosting a supermassive black hole (SMBH), are thought to form SMBH binaries. Motivated by recent observations from the East Asian VLBI Network (EAVN) showing periodic behavior in the M87 jet, a precession of about 11 years and a transverse oscillation of about 0.9 years, we constrain the mass of a hypothetical secondary black hole orbiting the primary SMBH in M87. To constrain the mass ratio between the primary SMBH ($M_{1}$) and the secondary black hole ($M_{2}$) defined a…

#devops rabbit hole for the weekend; Setting up a dependency analyser for monorepo. Turns out that with the right tools it’s not that difficult, and only costs the price of hosting some docker containers.
The parts of the puzzle are;

If you're in NorCal & like sushi, check out Tomisushi.
It's quite good - and authentic - especially for the price. Found myself surprised. [Japanese sushi & sake snob approved]

Meine nächste Folge Cyberpunk 2077 ist online.
Wir erleichtern die Welt um einen Snuff-Filmer, treffen Rogue, um von ihr etwas über Hellman zu erfahren, der den Relic Chip mitkonstruiert hat, und flanieren ein wenig durch Night City, über die Corpo Plaza... durch den Reconciliation Park... Heywood mit all seinen Gegensätzen.

The pink tax is the extra price women pay for products that are also marketed to men
— think shampoo or clothing.
Back in 2015, the New York City Department of Consumer Affairs found that across five industries, women were paying more for everyday products than men:
7 percent more for toys and accessories
8 percent more for adult clothing
13 percent more for personal care products
Although recent evidence suggests that the pink tax doesn’t apply to every pro…

How the “pink tariff” hurts women
Trump's trade war makes being a woman, and especially a Black woman, much more expensive.

This is an especially good time for you vacationers who plan to fly, because
the Reagan administration, as part of the same policy under which it
recently sold Yellowstone National Park to Wayne Newton, has "deregulated"
the airline industry. What this means for you, the consumer, is that the
airlines are no longer required to follow any rules whatsoever. They can
show snuff movies. They can charge for oxygen. They can hire pilots right
out of Vend…

Trinity VII. Predictions for the Observable Correlation Functions of Accreting Black Holes
The quasar correlation function assesses the occurrence of quasar pairs as a function of separation, which is strongly influenced by quasar host halo masses. The empirical Trinity model recently inferred the redshift-dependent relationship between supermassive black hole (SMBH) mass, galaxy mass, and halo mass, using constraints other than correlation functions (e.g., quasar luminosity functions, active galactic nuclei occupation fractions, and SMBH mass-bulge mass relations). Hence, comparing …

Predictions of the LSST Solar System Yield: Near-Earth Objects, Main Belt Asteroids, Jupiter Trojans, and Trans-Neptunian Objects
The NSF-DOE Vera C. Rubin Observatory is a new 8m-class survey facility presently being commissioned in Chile, expected to begin the 10yr-long Legacy Survey of Space and Time (LSST) by the end of 2025. Using the purpose-built Sorcha survey simulator (Merritt et al. In Press), and near-final observing cadence, we perform the first high-fidelity simulation of LSST's solar system catalog for key small body populations. We show that the final LSST catalog will deliver over 1.1 billion observations …
