The Identification of a Dusty Multiarm Spiral Galaxy at z = 3.06 with JWST and ALMA
The Astrophysical Journal Letters, 2022 Spiral arms serve crucial purposes in star formation and galaxy evolution. In this paper, we report the identification of “A2744-DSG- z 3,” a dusty, multiarm spiral galaxy at z = 3.059 using the James Webb Space Telescope (JWST) NIRISS imaging and grism ...

Exploring the star formation histories of galaxies [PDF]
, 1999 In this thesis, I explore the star formation histories of both spiral and elliptical galaxies. In Part 1,1 present an in-depth study of the star formation histories of spiral galaxies with a wide range of properties. Optical and near-infrared colours are

SPARC: MASS MODELS FOR 175 DISK GALAXIES WITH SPITZER PHOTOMETRY AND ACCURATE ROTATION CURVES [PDF]
, 2016 We introduce SPARC (Spitzer Photometry and Accurate Rotation Curves): a sample of 175 nearby galaxies with new surface photometry at 3.6 μm and high-quality rotation curves from previous H i/Hα studies.

Towards an Algorithmic Guide to Spiral Galaxies [PDF]
Theoretical Computer Science, 2014 In this paper, we are interested in the one-player game Spiral Galaxies, and study it from an algorithmic viewpoint. Spiral Galaxies has been shown to be NP-hard [Friedman, 2002] more than a decade ago, but so far it seems that no one has dared exploring its algorithmic universe. We take this trip and visit some of its corners.

A Constellation of Fluorescent Biosensors to Illuminate the Galaxy of Protein Kinases
ChemBioChem, Volume 27, Issue 11, 15 June 2026.Protein kinases (PKs) are enzymes that catalyze phosphorylation of protein substrates involved in a wide variety of biological signalling pathways. This review describes the different families and mechanisms of action and regulation of protein kinases, together with the different classes of fluorescent biosensors that have been engineered and ...

Six spiral galaxies lacking dark matter
Scientific ReportsDark matter is believed to be the essential building blocks of galaxy formation. While instances of galaxies lacking dark matter have been observed, these occurrences are typically linked to specific formation mechanisms, making them stand out as unique ...
