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

Galaxy growth in the concordance $\Lambda$CDM cosmology
, 2007 We use galaxy and dark halo data from the public database for the Millennium Simulation to study the growth of galaxies in the De Lucia et al. (2006) model for galaxy formation.

Formation Rates of Black Hole Accretion Disk Gamma-Ray Bursts [PDF]
, 1999 While many models have been proposed for GRBs, those currently favored are all based upon the formation of and/or rapid accretion into stellar mass black holes.

Galaxy mergers on a moving mesh: a comparison with smoothed particle hydrodynamics [PDF]
, 2013 Galaxy mergers have been investigated for decades using smoothed particle hydrodynamics (SPH), but recent work highlighting inaccuracies inherent in the traditional SPH technique calls into question the reliability of previous studies.

Galaxy Mergers Moulding The Cgm
, 2017 Galaxies are surrounded by sizeable gas reservoirs which host a significant amount of metals: the circum-galactic medium (CGM). The CGM acts as a mediator between the galaxy and the extra-galactic medium. However, our understanding of how galaxy mergers, a major evolutionary transformation, impact the CGM remains deficient.

FULLY COMPRESSIVE TIDES IN GALAXY MERGERS [PDF]
The Astrophysical Journal, 2009 The disruptive effect of galactic tides is a textbook example of gravitational dynamics. However, depending on the shape of the potential, tides can also become fully compressive. When that is the case, they might trigger or strengthen the formation of galactic substructures (star clusters, tidal dwarf galaxies), instead of destroying them.

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+

The Origins of Gas Accreted by Supermassive Black Holes: The Importance of Recycled Gas
The Astrophysical JournalWe investigate the fueling mechanisms of supermassive black holes (SMBHs) by analyzing 10 zoom-in cosmological simulations of massive galaxies, with stellar masses 10 ^11–12 M _⊙ and SMBH masses 10 ^8.9–9.7 M _⊙ at z = 0, featuring various major and ...

Tilted Dark Halos Are Common and Long-lived, and Can Warp Galactic Disks
The Astrophysical Journal Letters, 2023 In the Lambda cold dark matter paradigm, the dark halo governs the gravitational potential within which a galaxy can form and evolve. In this Letter we show that the present-day inner ( r < 50 kpc) dark halo can be significantly misaligned with the ...

Massive black hole binaries in gas-rich galaxy mergers; multiple regimes of orbital decay and interplay with gas inflows [PDF]
, 2013 We revisit the phases of the pairing and sinking of black holes (BHs) in galaxy mergers and circumnuclear discs in light of the results of recent simulations with massive BHs embedded in predominantly gaseous backgrounds.
