A Comprehensive Perturbative Formalism for Phase Mixing in Perturbed Disks. II. Phase Spirals in an Inhomogeneous Disk Galaxy with a Nonresponsive Dark Matter Halo

open access: yesThe Astrophysical Journal, 2023
We develop a linear perturbative formalism to compute the response of an inhomogeneous stellar disk embedded in a nonresponsive dark matter (DM) halo to various perturbations like bars, spiral arms, and encounters with satellite galaxies.

Dynamic regulation of the transcriptome and proteome of the equine embryo during maternal recognition of pregnancy

open access: yesFASEB BioAdvances, Volume 4, Issue 12, Page 775-797, December 2022., 2022
Abstract During initial maternal recognition of pregnancy (MRP), the equine embryo displays a series of unique events characterized by rapid blastocyst expansion, secretion of a diverse array of molecules, and transuterine migration to interact with the uterine surface.

The Subtle Effects of Mergers on Star Formation in Nearby Galaxies

open access: yesThe Astrophysical Journal, 2023
Interactions and mergers play an important role in regulating the physical properties of galaxies, such as their morphology, gas content, and star formation rate (SFR).

Optical Properties of 4248 IRAS Galaxies [PDF]

open access: yesMon.Not.Roy.Astron.Soc. 360 (2005) 322-339, 2005
We have investigated optical properties of 4248 infrared galaxies (IRGs) by positionally matching data from the IRAS and the SDSS DR3. Our sample includes 3 hyper luminous infrared galaxies (L >10^13Lsun) and 178 ultra luminous infrared galaxies (10^12Lsun < L < 10^13Lsun). Our findings are as follows: (i) more IR luminous galaxies tend to have smaller

THE IMPACT OF GALAXY INTERACTIONS ON ACTIVE GALACTIC NUCLEUS ACTIVITY IN zCOSMOS [PDF]

open access: yes, 2011
Close encounters between galaxies are expected to be a viable mechanism, as predicted by numerical simulations, by which accretion onto supermassive black holes can be initiated.

Galaxy And Mass Assembly (GAMA): the effect of close interactions on star formation in galaxies [PDF]

open access: yes, 2015
The modification of star formation (SF) in galaxy interactions is a complex process, with SF observed to be both enhanced in major mergers and suppressed in minor pair interactions.

The optical morphologies of the 2 Jy sample of radio galaxies: evidence for galaxy interactions [PDF]

open access: yes, 2010
We present deep Gemini Multi-Object Spectrograph South (GMOS-S)/Gemini optical broad-band images for a complete sample of 46 southern 2 Jy radio galaxies at intermediate redshifts (0.05

A Simulation of the Dependence of Tidal Interaction on Galaxy Type in Compact Groups [PDF]

open access: yesIJAA, 2024, 14, 85 - 100
We have investigated the role that different galaxy types have in galaxy-galaxy interactions in compact groups. N-body simulations of 6 galaxies consisting of a differing mixture of galaxy types were run to compare the relative importance of galaxy population demographic on evolution.

THE LAUNCHING OF COLD CLOUDS BY GALAXY OUTFLOWS. I. HYDRODYNAMIC INTERACTIONS WITH RADIATIVE COOLING [PDF]

open access: yes, 2015
To better understand the nature of the multiphase material found in outflowing galaxies, we study the evolution of cold clouds embedded in flows of hot and fast material.

Chiral Engineered Biomaterials: New Frontiers in Cellular Fate Regulation for Regenerative Medicine

open access: yesAdvanced Functional Materials, EarlyView.
Chiral engineered biomaterials can selectively influence cell behaviors in regenerative medicine. This review covers chiral engineered biomaterials in terms of their fabrication methods, cellular response mechanisms, and applications in directing stem cell differentiation and tissue function.
