The Zirconium (Z = 40) isotopic chain has attracted interest for more than four decades. The abrupt lowering of the energy of the first $2^+$ state and the increase in the transition strength B(E2; $2_1^\rightarrow 0_1^+$ going from $^{98}$Zr to $^{1

Black hole spin evolution across cosmic time from the NewHorizon simulation

Autor: Beckmann, Ricarda S., Dubois, Yohan, Volonteri, Marta, Dong-Paez, Chi An, Periani, Sebastien, Piotrowska, Joanna M, Martin, Garreth, Kraljic, Katharina, Devriendt, Julien, Peirani, Christophe, Yi, Sukyoung K

Astrophysical black holes (BHs) have two fundamental properties: mass and spin. While the mass-evolution of BHs has been extensively studied, much less work has been done on predicting the distribution of BH spins. In this paper we present the spin e

Exploring Active Galactic Nuclei and Little Red Dots with the Obelisk simulation

Autor: Volonteri, M., Trebitsch, M., Dubois, Y., Greene, J. E., Dong-Paez, C. -A., Habouzit, M., Lupi, A., Ma, Y., Beckmann, R. S., Dayal, P.

The James Webb Space telescope has discovered an abundant population of broad line emitters, typical signposts for Active Galactic Nuclei (AGN). Many of these sources have red colors and a compact appearance that has led to naming them `Little Red Do

Enhancement in neuromorphic NbO2 memristive device switching at cryogenic temperatures

Autor: Mburu, Ted, Robinson, Zachary R., Beckmann, Karsten, Lamba, Uday, Powell, Alex, Cady, Nathaniel, Sullivan, M. C.

The electrical properties and performance characteristics of niobium dioxide (NbO$_\mathrm{2}$)-based memristive devices are examined at cryogenic temperatures. Sub-stoichiometric Nb$_\mathrm{2}$O$_\mathrm{5}$ was deposited via magnetron sputtering a

To which reference class do you belong? Measuring racial fairness of reference classes with normative modeling

Autor: Rutherford, Saige, Wolfers, Thomas, Fraza, Charlotte, Harrnet, Nathaniel G., Beckmann, Christian F., Ruhe, Henricus G., Marquand, Andre F.

Reference classes in healthcare establish healthy norms, such as pediatric growth charts of height and weight, and are used to chart deviations from these norms which represent potential clinical risk. How the demographics of the reference class infl
