Forming Young Bulges within Existing Disks: Statistical Evidence for External Drivers

, 2003
Contrary to traditional models of galaxy formation, recent observations suggest that some bulges form within preexisting disk galaxies. Such late-epoch bulge formation within disks seems to be linked to disk gas inflow and central star formation, caused ...

Consequences of Mechanical and Radiative Feedback from Black Holes in Disc Galaxy Mergers [PDF]

, 2013
We study the effect of AGN mechanical and radiation feedback on the formation of bulge dominated galaxies via mergers of disc galaxies. The merging galaxies have mass-ratios of 1:1 to 6:1 and include pre-existing hot gaseous halos to properly account for

Gut microbiota and tuberculosis

iMeta, EarlyView.
This review explores the intricate relationship between gut microbiota (GM) and tuberculosis (TB). The figure illustrates the bidirectional effects between GM dynamics and TB progression, as well as the interactions between the GM and antituberculosis drugs.

Circulating Tumor DNA as a Marker of Recurrence Risk in Stage III Colorectal Cancer: The α‐CORRECT Study

Journal of Surgical Oncology, EarlyView.
ABSTRACT Background and Objectives Identification of colorectal cancer (CRC) patients at high risk of recurrence could be of substantial clinical use. We evaluated the association of ctDNA status, using a tumor‐informed assay, with recurrence‐free survival (RFS). Methods Stage III CRC patients were enrolled between 2016 and 2020.

Merging Gas-rich Galaxies That Harbor Low-luminosity Twin Quasars at z = 6.05: A Promising Progenitor of the Most Luminous Quasars

The Astrophysical Journal
We present Atacama Large Millimeter/submillimeter Array [C ii ] 158 μ m line and underlying far-IR continuum emission observations (0.″57 × 0.″46 resolution) toward a quasar–quasar pair system recently discovered at z = 6.05. The quasar nuclei (C1 and C2)

Anti‐Pseudomonas Aeruginosa Bacteriophage Loaded Electrospun Fibers for Antibacterial Wound Dressings

Macromolecular Rapid Communications, EarlyView.
Multidrug resistant Pseudomonas (P.) aeruginosa is detected in many infected wounds and is challenging to treat with antibiotics. As an alternative, this work incorporates anti‐P. aeruginosa Neko phages into electrospun fibres to explore their potential for treating infected wounds.

The Most Massive Early-type Galaxies Exhibit Tidal Features More Frequently in Lower-density Environments

The Astrophysical Journal
The most massive early-type galaxies (ETGs) are known to form through numerous galaxy mergers. Thus, it is intriguing to study whether their formation in low-density environments, where nearby companions are almost absent, is associated with mergers ...

Close Pairs as Proxies for Galaxy Cluster Mergers

, 2008
Galaxy cluster merger statistics are an important component in understanding the formation of large-scale structure. Unfortunately, it is difficult to study merger properties and evolution directly because the identification of cluster mergers in ...

Behavioural and physiological responses of chacma baboons (Papio ursinus) to human‐induced mortality in anthropogenically modified habitat

People and Nature, EarlyView.
Abstract As a result of expanding human populations and the anthropogenic modification of natural habitats, many wildlife populations are living in increasing proximity to humans. While this may provide benefits to some species through increased access to resources, sharing space and resources often leads to negative interactions or ‘conflict’ between ...

Buried AGNs in Advanced Mergers:Mid-infrared color selection as a dual AGN finder

, 2017
A direct consequence of hierarchical galaxy formation is the existence of dual supermassive black holes (SMBHs), which may be preferentially triggered as active galactic nuclei (AGN) during galaxy mergers. Despite decades of searching, however, dual AGNs
