Detecting Intermediate-Mass Black Holes out to 20 Mpc with ELT/HARMONI: The Case of FCC 119

Universe
Intermediate-mass black holes (IMBHs; MBH≈103–5 M⊙) play a critical role in understanding the formation of supermassive black holes in the early universe.

Effects of Dietary Mannan Oligosaccharides on Growth, Disease Resistance, and Gut Microbiota in Zebrafish

Animal Research and One Health, EarlyView.
Supplementation with mannan oligosaccharides (MOS) enhances growth, disease resistance, antioxidant capacity, and gut microbiota diversity while suppressing inflammation, apoptosis, and strengthening intestinal barrier integrity in zebrafish challenged with LPS or DSS.

Photometry and Classification of Stars in the Direction of Clusters NGC 7129 and NGC 7142 in Cepheus. I. Magnitudes, Color Indices and Spectral Types of 2140 Stars

Open Astronomy, 2012
In a 1.5 square degree area, centered at RA = 21:44:30, DEC = +65:58, we have determined magnitudes and color indices for 2140 stars in the Vilnius seven-color system down to V = 17 mag.

Principal Component‐Based Classification of Blazar Candidates of Uncertain Type in the 4FGL/LAT

Astronomische Nachrichten, EarlyView.
ABSTRACT We adopted principal component analysis (PCA), linear discriminant analysis (LDA), and support vector machines (SVM), to study classification for a sample of 2708 Fermi blazars: 1142 BL Lac objects (BLLs), 759 flat spectrum radio quasars (FSRQs), and 807 blazar candidates of uncertain type (BCUs).

Communication rules regarding support seeking in patients with a physical illness, according to people with a Surinamese or a Dutch cultural background

Journal of Migration and Health
Objective: People with different cultural backgrounds can evaluate the appropriateness of direct and indirect support seeking differently. In this study we explored how direct and indirect communication rules for verbal support seeking by patients with ...

Star Formation Histories with Gaia: The Galaxy and Beyond

Open Astronomy, 2003
ESA’s Gaia mission will provide accurate astrometric, photometric and spectroscopic data for millions of stars in the Galaxy and beyond. We discuss the prospects of using this vast amount of astrophysical information for understanding star formation ...

Asymmetric Star Formation Efficiency Due to Ram Pressure Stripping

Galaxies, 2016
Previous works have shown that a dense cluster environment affects satellite galaxy properties and accelerates or truncates their evolutionary processes.

Direct SMBH Formation Driven by Runaway Stellar Collisions in Globally Unstable Stellar Systems

Astronomische Nachrichten, EarlyView.
ABSTRACT The fueling problem addresses the ultimate fate of the reservoirs of gas and stars driven into the deepest gravitational potential wells of galaxies, thus it may contain the Universe's densest concentrations of gas and stars. This raises a key question: does the infalling material collapse directly into a supermassive black hole, or can it ...

The Evolution of Galaxy Groups and of Galaxies Therein [PDF]

, 2007
Properties of groups of galaxies depend sensitively on the algorithm for group selection, and even the most recent catalogs of groups built from redshift-space selection should suffer from projections and infalling galaxies. The cosmo-dynamical evolution of groups from initial Hubble expansion to collapse and virialization leads to a fundamental track (
