Overmassive and Undermassive Massive Black Holes: The Role of Environment and Gravitational-Wave Recoils

Astronomy & Astrophysics
Understanding the connection between galaxy properties and their central massive black holes (MBHs) is key to unveiling their co-evolution. We use the L-Galaxies-BH semi-analytical model and the Millennium suite of simulations to investigate the physical

Strength‐Based Parenting and Relationship Quality in Latine Families Facing Justice System Risk

Family Relations, EarlyView.
ABSTRACT Objective To examine whether parenting practices that are shaped by culturally embedded value systems (responsiveness, autonomy granting, and affective warmth) and familism are associated with parent–adolescent relationship quality among Latine youth, and whether these associations differ by youth justice involvement and gender.

A Low-mass Model of the Milky Way: The Disk Warp Resulting from a Galaxy Merger

The Astrophysical Journal
Previous studies have shown that disk warps can result from galaxy mergers. Recent research indicates a noticeable decline in the rotation curve (RC) of the Milky Way, suggesting the need for a new low-mass model to describe its dynamical features.

Mergers and risk [PDF]

This paper examines the impact of mergers on default risk, finding that, on average, a merger increases the default risk of the acquiring firm. This is surprising for two reasons: risk reduction is among the reasons commonly cited for mergers, and asset ...

Modular training resources for bioimage analysis

Journal of Microscopy, EarlyView.
Abstract Modern microscopy enables us to measure structural and dynamical properties of many biological processes and is therefore an indispensable research tool. However, the amount and complexity of the produced imaging data is steadily increasing.

GloBIAS survey results – An insight into the global bioimage analysis community

Journal of Microscopy, EarlyView.
Abstract There is a global need for bioimage analysis (BIA) as advances in life sciences increasingly rely on cutting‐edge imaging systems that have dramatically expanded the complexity and dimensionality of biological images. Turning these data into scientific discoveries requires scientists with effective data management skills and knowledge of state‐

Reduction of the Bar Fraction in Paired Galaxies in the SDSS

The Astrophysical Journal
We investigate the bar fraction in galaxy pairs from the Sloan Digital Sky Survey to assess how galaxy interactions affect bar structures. Compared to isolated galaxies, close pairs exhibit a significantly reduced bar fraction at projected separations ...

Bioimage management and analysis in Galaxy: Tools, workflows, training, and community practices

Journal of Microscopy, EarlyView.
ABSTRACT Image analysis in the life sciences is constrained by fragmented software ecosystems, heterogeneous data formats, and limited reproducibility. These barriers hinder the reuse of image analysis methods and the sustainability of tools. In this article, we describe how the Galaxy platform enables FAIR (Findable, Accessible, Interoperable, and ...

The Origins of Gas Accreted by Supermassive Black Holes: The Importance of Recycled Gas

The Astrophysical Journal
We investigate the fueling mechanisms of supermassive black holes (SMBHs) by analyzing 10 zoom-in cosmological simulations of massive galaxies, with stellar masses 10 ^11–12 M _⊙ and SMBH masses 10 ^8.9–9.7 M _⊙ at z = 0, featuring various major and ...

Photochemical effects of Mars‐like UV irradiation on carboxylic acids in carbonaceous chondrites and expectations for abiotic background organics on Mars

Meteoritics &Planetary Science, EarlyView.
Abstract In the search for life on Mars, understanding the origin of preserved organics is critical. Expected sources include exogenous delivery, endogenous synthesis, and potentially life. Environmental processing by ultraviolet (UV) irradiation can alter these organics, obscuring hallmarks of their origin. To deconvolve these effects, we conducted an
