Bulgeless Evolution And the Rise of Discs (BEARD)

open access: yesAstronomy & Astrophysics
Aims. The existence of massive disc galaxies with little or no bulge challenges conventional Λ cold dark matter model, which typically favours dynamically hot central structures due to early collapse and mergers.

Recognition of the interiors of de Sitter-Kerr black holes from their shadows [PDF]

open access: yesAsymmetry
We investigate the asymmetry of shadows of rotating black holes, as a source of information on their interior content, for black holes of the Kerr-Schild class, specified by Ttt = Trr.

Broad-line AGNs at 3.5 < z < 6: The Black Hole Mass Function and a Connection with Little Red Dots

open access: yesAstrophysical Journal
We present a sample of 62 Hα detected broad-line active galactic nuclei (BLAGNs) at redshifts 3.5 < z < 6.8 using data from the CEERS and RUBIES surveys. We select these sources directly from JWST/NIRSpec G395M/F290LP spectra.

Evidence for Universality in the Initial Planetesimal Mass Function [PDF]

open access: yes, 2017
Planetesimals may form from the gravitational collapse of dense particle clumps initiated by the streaming instability. We use simulations of aerodynamically coupled gas–particle mixtures to investigate whether the properties of planetesimals formed in ...

The soft scalar mass β-function [PDF]

open access: yesPhysics Letters B, 1998
We present an exact formula for the $β$-function for the soft-breaking scalar mass in an N=1 supersymmetric gauge theory, in the form of an operator acting on the anomalous dimension. In particular we give the exact form for the correction due to the $ε$-scalar mass, and show that it has a particularly simple form in the renormalisation scheme ...

The HST-Hyperion survey: Environmental imprints on the stellar mass function at z  ∼  2.5

open access: yesAstronomy & Astrophysics
Context. Not all galaxies at cosmic noon (2 ≲ z ≲ 3) evolve in the same way. Particularly, it remains unclear how and to what extent the local environment – especially the extreme overdensities of protoclusters – affects the stellar mass assembly of its ...

Mounting, structure and autocleavage of a type VI secretion-associated Rhs polymorphic toxin

open access: yesNature Communications, 2021
Rearrangement hot spots (Rhs) proteins are bacterial polymorphic toxin systems. Here, the authors show that Rhs1 forms a complex with the Type VI secretion system (T6SS) spike protein VgrG and the EagR chaperone.

Ordered Probability Mass Function

open access: yesCoRR, 2013
Suppose that in the four tests Alice's scores are 90, 95, 85, 90, and Bob's scores are 85, 95, 90, 90. How to evaluate their scores? In this paper, we introduce the concept of ordered probability mass function which can be used to find a probability mass function with smaller variance.

A simple matter of life and death : the trials of postnatal beta-cell mass regulation [PDF]

open access: yes, 2012
Pancreatic beta-cells, which secrete the hormone insulin, are the key arbiters of glucose homeostasis. Defective beta-cell numbers and/or function underlie essentially all major forms of diabetes and must be restored if diabetes is to be cured. Thus, the
