Wandering globular clusters: the first dwarf galaxies in the universe?
, 2010 In the last decade we witness an advent of new types of dwarf stellar systems in cluding ultra-compact dwarfs, ultra-faint dwarf spheroidals, and exotic globular clusters, breaking the old simple paradigm for dwarf galaxies and globular clusters.

Star Formation in Dwarf Galaxies [PDF]
, 1998 We explore mechanisms for the regulation of star formation in dwarf galaxies. We concentrate primarily on a sample in the Virgo cluster, which has HI and blue total photometry, for which we collected H$\alpha$ data at the Wise Observatory.

The Vegan Villain Sets Out to The End of Summer: Functionalized Coatings as Biohybrid UV‐Sensors
Advanced Materials Interfaces, EarlyView.This study introduces biohybrid coatings incorporating E. coli biomass expressing photoconvertible fluorescent proteins as UV‐A responsive elements. Upon irradiation at 400 nm, the coatings exhibit an irreversible fluorescence shift from green to red within 15 min. Notably, the photoconversion capability is retained after >1 year of storage.

Discovery of a Double-core Dwarf Galaxy in a Major Wet Merger: MCG+08-16-005
The Astronomical JournalI present the discovery of a dwarf galaxy with double cores, MCG+08-16-005, observed by an Integral Field Unit. Based on photometric and spatially resolved spectroscopic analyses, the galaxy is suggested as an ongoing dwarf-dwarf merger. MCG+08-16-005 is

, 2010 We present ultraviolet (UV) color-magnitude relations (CMRs) of early-type dwarf galaxies in the Virgo cluster, based on Galaxy Evolution Explorer (GALEX) UV and Sloan Digital Sky Survey (SDSS) optical imaging data. We find that dwarf lenticular galaxies

Chemical evolution of dwarf irregular and blue compact galaxies [PDF]
Astronomy & Astrophysics, 2011 Dwarf irregular and blue compact galaxies are very interesting objects since they are relatively simple and unevolved. We present new models for the chemical evolution of these galaxies by assuming different regimes of star formation (bursting and continuous) and different kinds of galactic winds (normal and metal-enhanced).

Circularly Polarized Structural Color Pigments Tunable Across the Full Visible Spectrum
Advanced Optical Materials, EarlyView.By infusing black dye into spherical shells of polymerized cholesteric liquid crystal, blue, green and red omnidirectional retroreflectors of circularly polarized structural color are achieved. They can be laid out on arbitrary surfaces without any need for index matching binder to define graphical information for robots and Augmented Reality devices ...

Albus 1: A very bright white dwarf candidate
, 2007 We have serendipitously discovered a previously-unknown, bright source (B_T = 11.75+/-0.07 mag) with a very blue V_T-K_s color, to which we have named Albus 1.

The Next Generation Virgo Cluster Survey. VI. The Kinematics of Ultra-compact Dwarfs and Globular Clusters in M87 [PDF]
, 2015 The origin of ultra-compact dwarfs (UCDs)--objects larger and more massive than typical globular clusters (GCs), but more compact than typical dwarf galaxies--has been hotly debated in the 15 years since their discovery.
