Two characteristics of thick disks formed through minor mergers: Orbital eccentricities and stellar excess

EPJ Web of Conferences, 2012
In this contribution, we will present two results we have recently obtained in studying the impact of satellite(s) accretions on stellar disks, and that concern: (1) the distribution of the eccentricities of stars in thick disks; (2) the characteristics ...

An Integrated Transient Expression and UPLC-PDA Approach for Functional Genomics and Metabolic Analysis of Cannabis sativa. [PDF]

Biotechnol J
Graphical Abstract and Lay Summary Cannabis research is limited by a lack of efficient tools for studying gene function and metabolism. We developed two rapid, high‐efficiency methods for transient gene expression in high‐THC Cannabis and a simple, cost‐effective method to measure cannabinoids and cannflavins.

Electronics-Free Visual Monitoring of Dry Eye Disease-Related Tear Biomarkers Using Smart Scleral Lenses. [PDF]

Adv Sci (Weinh)
An electronics‐free smart scleral lens passively monitors dry eye disease‐related tear biomarkers through colorimetric sensing of chloride, pH, and ocular surface temperature. Smartphone‐assisted image analysis enables quantitative interpretation, providing a simple, non‐invasive strategy for ocular health monitoring without integrated electronics ...

A Rest-frame Near-IR Study of Clumps in Galaxies at 1 < z < 2 Using JWST/NIRCam: Connection to Galaxy Bulges

The Astrophysical Journal, 2023
A key question in galaxy evolution has been the importance of the apparent “clumpiness” of high-redshift galaxies. Until now, this property has been primarily investigated in rest-frame UV, limiting our understanding of their relevance.

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 ...

XUE: Molecular Inventory in the Inner Region of an Extremely Irradiated Protoplanetary Disk

The Astrophysical Journal Letters, 2023
We present the first results of the eXtreme UV Environments (XUE) James Webb Space Telescope (JWST) program, which focuses on the characterization of planet-forming disks in massive star-forming regions.

Hidden Imprints of Minor Merging in Early-Type Galaxies: Inner Polar Rings and Inclined Large-Scale Gaseous Disks In S0s

Galaxies, 2015
I discuss my latest observational data and ideas about decoupled gaseous subsystems in nearby lenticular galaxies. As an extreme case of inclined gaseous disks, I demonstrate a sample of inner polar disks, derive their incidence, about 10% among the ...

Similar Signatures of Coplanar Gas Inflow and Disk Warps in Galactic Gas Kinematic Maps

The Astrophysical Journal, 2023
Hydrodynamic simulations suggest that galactic gas disks form when coplanar gas spirals into the inner regions of the disk. We recently presented a simple modified accretion disk model of viscous galactic disks in which star formation is fed by a radial ...
