The Remarkable Predictive Power of Infrared Data of Blazars

The Astrophysical Journal
Blazars are the brightest and most abundant persistent sources in the extragalactic γ -ray sky. Due to their significance, they are often observed across various energy bands, where the data of which can be used to explore potential correlations between ...

Characterization of the Cubamyces Menziesii Terpenome

ChemBioChem, EarlyView.
The genome of Cubamyces menziesii reveals 18 putative sesquiterpene cyclase genes. These genes are cloned and expressed in Escherichia coli, yielding 10 active enzymes. Using farnesyl diphosphate as substrate, the enzymes are analyzed, and the products characterized after bioconversion, uncovering diverse sesquiterpene structures. This study highlights

Active and Merging Galaxies

, 2015
Galaxy close pairs are studied to investigate the effects of gravitational interactions on star formation and black hole accretion processes in merger progenitors. We derive star formation rates from near-ultraviolet luminosities; this is a new method for studying mergers and provides unique insight into recent star formation rates.

C13‐Deacylase from Nocardioides albus Resp. Streptomyces sp., Catalyzing Side Chain Hydrolysis on the Taxane Core

ChemCatChem, EarlyView.
An enzyme that has been identified and characterized as capable of hydrolyzing paclitaxel (Taxol), a key anticancer drug derived from Pacific yew (Taxus brevifolia) has been identified. Molecular docking (MD) simulations map the catalytic triad and critical residues that drive substrate‐enzyme interactions. The findings indicate the catalytic potential

Blowing Star Formation Away in AGN Hosts (BAH). II. Investigating the Origin of the H2 Emission Excess in Nearby Galaxies with JWST MIRI

The Astrophysical Journal
We use James Webb Space Telescope Mid-Infrared Instrument Medium-resolution Spectrometer observations of 3C 293 (UGC 8782), CGCG 012-070 and NGC 3884 to investigate the origin of the H _2 emission.

Theoretical Re-evaluations of Scaling Relations between SMBHs and Their Host Galaxies–2. Importance of AGN Feedback Suggested by Stellar Age–Velocity Dispersion Relation

Frontiers in Astronomy and Space Sciences, 2017
We present the galactic stellar age—velocity dispersion relation obtained from a semi-analytic model of galaxy formation. We divide galaxies into two populations: galaxies which have over-massive/under-massive black holes (BHs) against the best-fitting ...

Narrow-line Seyfert 1 Galaxies and the M_BH - sigma Relation

, 2007
We have studied the location of narrow-line Seyfert 1 (NLS1) galaxies and broad-line Seyfert 1 (BLS1) galaxies on the M_BH - sigma relation of non-active galaxies.

LGBTQ+ Affirmative Care Training in Counselor Education: A Community‐Based Inquiry

Counselor Education and Supervision, EarlyView.
ABSTRACT Counselor educators, counselors‐in‐training, and LGBTQ+ community members engaged in a community‐based qualitative inquiry exploring LGBTQ+ affirmative care education. Findings revealed counselor educators’ components and delivery of content, developmental implications for applying LGBTQ+ affirmative care, and gaps between education and LGBTQ+

Overmassive Black Holes at Cosmic Noon: Linking the Local and the High-redshift Universe

The Astrophysical Journal Letters
We report for the first time a sample of 12 supermassive black holes (SMBHs) hosted by low-mass galaxies at cosmic noon, i.e., in a redshift range consistent with the peak of star formation history: z ∼ 1–3.
