A Luminous X-Ray Active Galactic Nucleus in the Dwarf–Dwarf Galaxy Merger RGG 66

The Astrophysical Journal
We present the discovery of a luminous X-ray active galactic nucleus (AGN) in the dwarf galaxy merger RGG 66. The black hole is predicted to have a mass of M _BH ∼ 10 ^5.4 M _⊙ and to be radiating close to its Eddington limit ( L _bol / L _Edd ∼ 0.75 ...

The zCOSMOS redshift survey : Influence of luminosity, mass and environment on the galaxy merger rate

, 2011
The contribution of major mergers to galaxy mass assembly along cosmic time is an important ingredient to the galaxy evolution scenario. We aim to measure the evolution of the merger rate for both luminosity/mass selected galaxy samples and investigate ...

Gut Mycobiota of Three Rhinopithecus Species Provide New Insights Into the Association Between Diet and Environment

Integrative Zoology, EarlyView.
This study revealed the basic structures of gut mycobiota of three wild Rhinopithecus species. The gut mycobiota of Rhinopithecus showed close connection with their feeding habits, and there were associations between gut mycobiota and the host's living environments.

A Study of the Merging Dwarf Galaxy VCC322

The Astrophysical Journal
Galaxy interactions and mergers can enhance or reduce star formation, but a complete understanding of the involved processes is still lacking. The effect of dwarf galaxy mergers is even less clear than their massive counterpart.

WIMANET: The Power of a Network in Wildlife Malaria Research

Integrative Zoology, EarlyView.
The Wildlife Malaria Network (WIMANET) is an EU‐COST funded global network of researchers and stakeholders interested in wildlife malaria and related haemosporidian parasites. In this paper, we review WIMANET's activities to date. We hope this encourages new members to join the network and motivates both new and existing members to participate in its ...

CEERS Key Paper. IX. Identifying Galaxy Mergers in CEERS NIRCam Images Using Random Forests and Convolutional Neural Networks

The Astrophysical Journal Letters
A crucial yet challenging task in galaxy evolution studies is the identification of distant merging galaxies, a task that suffers from a variety of issues ranging from telescope sensitivities and limitations to the inherently chaotic morphologies of ...

AGN Feedback Signatures in UV Emission

Galaxies
Supermassive black holes (SMBH) are believed to influence galaxy evolution through AGN (active galactic nuclei) feedback. Galaxy mergers are key processes of galaxy formation that lead to AGN activity and star formation.

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.
