DATA MINING THE GALAXY ZOO MERGERS [PDF]

, 2020
. Collisions between pairs of galaxies usually end in the coalescence (merger) of the two galaxies. Collisions and mergers are rare phenomena, yet they may signal the ultimate fate of most galaxies, including our own Milky Way.

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.

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

Response of Fecal Bacteria and Fungi to Tannin‐Rich Diets in Sika Deer (Cervus nippon): Evidence from Both Feeding Experiments and Field Investigations

Integrative Zoology, EarlyView.
Feeding with tannin‐rich diets altered the fecal microbial composition and increased the relative abundance of tannin‐degrading microbes. We hypothesize that fecal bacteria and fungi may play important roles in helping herbivores adapt to tannin‐rich diets but respond to different tannin concentrations varies.

Radial Distributions of Star Formation and Gas-phase Metallicity in Spiral–Elliptical Galaxy Pairs

The Astrophysical Journal
Using integral-field spectroscopy from the fourth-generation Sloan Digital Sky Survey Mapping Nearby Galaxies at Apache Point Observatory, we investigate the radial distributions of the star formation rates (SFRs) and gas-phase metallicities in spiral ...

Genotyping Contemporary Captive and Historical Wild Western Lowland Gorillas Indicates Captive Breeding Is Maintaining Genetic Diversity in a Critically Endangered Primate

Animal Conservation, EarlyView.
Captive populations of threatened species risk losing genetic diversity over time. We evaluated the genetic status of contemporary captive western lowland gorillas (Gorilla gorilla gorilla) at Howletts and Port Lympne and compared this with specimens from a historical wild population.

JWST Unveils the Bimodal Nature of Lyα Emitters at 3 < z < 7: Pristine versus Merger-driven Populations

The Astrophysical Journal
We present a systematic study of merging galaxies among Lyα emitters (LAEs) using James Webb Space Telescope/NIRCam high-resolution imaging data. From a large sample of 817 spectroscopically confirmed LAEs at 3  6 to 70% at z

Story2Board: A Training‐Free Approach for Expressive Visual Storytelling

Computer Graphics Forum, EarlyView.
Abstract We present Story2Board, a training‐free framework for expressive storyboard generation from natural language. Existing methods narrowly focus on subject identity, overlooking key aspects of visual storytelling such as spatial composition, background evolution, and narrative pacing.

DiskScissors: Cutting Arbitrary‐Topology Solids for Bijective Mapping

Computer Graphics Forum, EarlyView.
Abstract An algorithm for cutting solid objects in a topology‐controlled manner is presented. Concretely, given a loop on the object boundary, a disk‐topology cut surface bounded by the loop is constructed in the interior. In contrast to various previous approaches, both disk topology and conformance to the prescribed loop are ensured by construction ...

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 ...
