Ultra Short Pulse Laser Welding of Glass to Metal in the Low Fluence Regime
Laser &Photonics Reviews, EarlyView.Ultrashortpulse laser welding enables precise joining of glass and metal with minimal thermal damage. We introduce the TwoThresholds Criteria to identify suitable laser parameters by combining the nonlinearabsorption threshold in glass with the metalmodification fluence threshold.

Astrophysical Journal Letters, 2022 Abstract Single flux density measurements at observed-frame submillimeter and millimeter wavelengths are commonly used to probe dust and gas masses in galaxies. In this Letter, we explore the robustness of this method to infer dust mass, focusing on quiescent galaxies, using a series of controlled experiments on four massive halos from ...

The Brightest Galaxies in the Dark Ages: Galaxies’ Dust Continuum Emission during the Reionization Era [PDF]
Astrophysical Journal, 2018 Abstract Though half of cosmic starlight is absorbed by dust and reradiated at long wavelengths (3 μm–3 mm), constraints on the infrared through the millimeter galaxy luminosity function (or the “IRLF”) are poor in comparison to the rest-frame ultraviolet and optical galaxy luminosity functions, particularly at z ≳ 2.5.

Astrophysical Journal, 2020 Abstract We compare the extent of the dust, molecular gas, and stars in three star-forming galaxies, at z = 1.4, 1.6, and 2.7, selected from the Hubble Ultra Deep Field based on their bright carbon monoxide (CO) and dust-continuum emission as well as their large rest-frame optical sizes. The galaxies have high stellar masses,

ALMA Observation of NGC 5135: The Circumnuclear CO (6–5) and Dust Continuum Emission at 45 pc Resolution* [PDF]
Astrophysical Journal, 2018 Abstract We present high-resolution (0.″17 × 0.″14) Atacama Large Millimeter/submillimeter Array (ALMA) observations of the CO (6–5) line and 435 μm dust continuum emission within a ∼9″ × 9″ area centered on the nucleus of the galaxy NGC 5135.

The continuum approximation is used to analyze the effect of electron emission from the surface of a spherical dust grain immersed in a plasma on the grain charge by assuming negligible ionization and recombination in the disturbed plasma region around the grain.

Bolocam Survey for 1.1 mm Dust Continuum Emission in the c2d Legacy Clouds. I. Perseus [PDF]
Astrophysical Journal, 2006 We have completed a 1.1 mm continuum survey of 7.5 sq deg of the Perseus Molecular Cloud using Bolocam at the Caltech Submillimeter Observatory. This represents the largest millimeter or submillimeter continuum map of Perseus to date. Our map covers more than 30,000 31" (FWHM) resolution elements to a 1 sigma RMS of 15 mJy/beam.

THE BOLOCAM GALACTIC PLANE SURVEY: λ = 1.1 AND 0.35 mm DUST CONTINUUM EMISSION IN THE GALACTIC CENTER REGION [PDF]
Astrophysical Journal, 2010 The Bolocam Galactic Plane Survey (BGPS) data for a six square degree region of the Galactic plane containing the Galactic center is analyzed and compared to infrared and radio continuum data. The BGPS 1.1 mm emission consists of clumps interconnected by a network of fainter filaments surrounding cavities, a few of which are filled with diffuse near-IR

Millimeter Dust Continuum Emission as a Tracer of Molecular Gas in Galaxies
2008Molecular gas in galaxies is the primary fuel of star formation but the exact amount of molecular gas remains unknown since H_2 is not observed directly in cold interstellar regions. CO observations have been so far the best way to trace molecular gas in external galaxies, but in low metallicity environments the gas mass deduced could be largely ...
