Very Long Baseline Interferometry Detection of an Active Radio Source Potentially Driving 100 kpc Scale Emission in the Ultraluminous Infrared Galaxy IRAS F01004–2237

The Astrophysical Journal
The nearby ultraluminous infrared galaxy (ULIRG) IRAS F01004−2237 exhibits 100 kpc scale continuum emission at radio wavelengths. The absence of extended X-ray emission in IRAS F01004−2237 has suggested an active galactic nucleus (AGN) origin for the ...

Atomic Size Misfit for Electrocatalytic Small Molecule Activation

Advanced Functional Materials, EarlyView.
This review explores the application and mechanisms of atomic size misfit in catalysis for small molecule activation, focusing on how structural defects and electronic properties can effectively lower the energy barriers of chemical bonds in molecules like H2O, CO2, and N2.

An Ultradeep Multiband Very Large Array Survey of the Faint Radio Sky (COSMOS-XS): New Constraints on the Optically Dark Population

The Astrophysical Journal, 2023
Attempts to trace star formation with rest-frame UV/optical observations at redshifts z > 2 are affected by the presence of potentially substantial, yet uncertain, dust attenuation.

Star formation in bulgeless late type galaxies: clues to their evolution

, 2012
We present GMRT 1280 MHz radio continuum observations and follow-up optical studies of the disk and nuclear star formation in a sample of low luminosity bulgeless galaxies. The main aim is to understand bulge formation and overall disk evolution in these

Hot gas and dust in a protostellar cluster near W3(OH [PDF]

, 1999
We used the IRAM Interferometer to obtain sub-arcsecond resolution observations of the high-mass star-forming region W3(OH) and its surroundings at a frequency of 220 GHz.

Locating the Youngest HII Regions in M82 with 7 mm Continuum Maps

, 2009
We present 7mm Very Large Array continuum images of the starburst galaxy M82. On arcsecond scales, two-thirds of the 7mm continuum consists of free-free emission from HII regions.

Evolving Platinum‐Copper Nanostructures for Enhanced Photothermal Therapy and Controlled Copper Release in Cancer Therapy

Advanced Functional Materials, EarlyView.
Platinum‐Copper bimetallic nanoparticles may evolve depending on their synthesis under tumor microenvironment conditions and play a dual role as chemotherapeutic agents after releasing Cu ions and as near infrared photothermal agents with the Pt‐rich remaining frames.
