Selecting Clusters and Protoclusters via Stellar Mass Density: II. Application to HSC-SSP Observations
We present a selection of candidates of clusters and protoclusters of galaxies identified in the photometric data of the HSC-SSP Wide Public Data Release 3 (PDR3), spanning the redshift range $\rm 0.1 \leq z \leq 2$. The selection method, detailed in Vicentin et al. (2025), involves detecting massive galaxies located in high-density regions of matter, identified as potential central dominant galaxies, i.e., (proto)BCGs. Probabilistic criteria based on proximity to the candidate central galaxy a…

Modeling Epidemics on Multiplex Networks: Epidemic Threshold and Basic Reproduction Number
Accurate epidemic forecasting requires models that account for the layered and heterogeneous nature of real social interactions. The basic reproduction number $\mathcal R_0$ calculated from models that assume homogeneous mixing or single-layer contact structures have limited applicability to complex social systems. Here, we propose an expression of $\mathcal R_0$ in the context of multiplex networks, enabling the analysis of disease transmission across multiple social layers. We adapt the Deg…

Psalm 58 is about the maga-klan... Here it is (slightly shorted to meet my Mastodon site's posting length limits.)

Do you rulers indeed speak justly? Do you judge people with equity?
No, in your heart you devise injustice, and your hands mete out violence on the earth.

Break the teeth in their mouths, O God;
Lord, tear out the fangs of those lions!
Let them vanish like water that flows away; when they draw the bow, let their arrows fall s…

Bible Gateway passage: Psalm 58 - New International Version
Psalm 58 - For the director of music. To the tune of “Do Not Destroy.” Of David. A miktam. Do you rulers indeed speak justly? Do you judge people with equity? No, in your heart you devise injustice, and your hands mete out violence on the earth. Even from birth the wicked go astray; from the womb they are wayward, spreading lies. Their venom is like the venom of a snake, like that of a cobra that has stopped its ears, that will not heed the tune of the charmer, however skillful the enchante…

GRB 250702B: Discovery of a Gamma-Ray Burst from a Black Hole Falling into a Star
Gamma-ray bursts are the most luminous electromagnetic events in the universe. Their prompt gamma-ray emission has typical durations between a fraction of a second and several minutes. A rare subset of these events have durations in excess of a thousand seconds, referred to as ultra-long gamma-ray bursts. Here, we report the discovery of the longest gamma-ray burst ever seen with a ~25,000 s gamma-ray duration, GRB 250702B, and characterize this event using data from four instruments in the Int…

Irony at z=6.68: a bright AGN with forbidden Fe emission and multi-component Balmer absorption
We present the deepest medium-resolution JWST/NIRSpec spectroscopy to date of a bright Little Red Dot (LRD) AGN, Irony at z=6.68. The data reveal broad Balmer emission from H$α$-H$δ$ and Balmer absorption in H$α$-H$ε$. The absorption lines are kinematically split: H$α$ is blueshifted while higher-order lines are redshifted suggesting complex gas kinematics; their relative ratios are inconsistent with a single, passive absorbing screen. The line depths require absorption of both the BLR and…

BlackTHUNDER: Shedding light on a dormant and extreme little red dot at z=8.50
Recent photometric surveys with JWST have revealed a significant population of mysterious objects with red colours, compact morphologies, frequent signs of active galactic nucleus (AGN) activity, and negligible X-ray emission. These 'Little Red Dots' (LRDs) have been explored through spectral and photometric studies, but their nature is still under debate. As part of the BlackTHUNDER survey, we have observed UNCOVER_20466, the second most distant LRD known (z=8.5), with the JWST/NIRSpec IFU. Pr…
