EESSI: A cross‐platform ready‐to‐use optimised scientific software stack
Software: Practice and Experience, Volume 53, Issue 1, Page 176-210, January 2023., 2023 Abstract Getting scientific software installed correctly and ensuring it performs well has been a ubiquitous problem for several decades now, which is compounded currently by the changing landscape of computational science with the (re‐)emergence of different microprocessor families, and the expansion to additional scientific domains like artificial ...

Radio Continuum Observations of the Nuclei of Nearby Galaxies [PDF]
Symposium - International Astronomical Union, 1982 A survey has been carried out at Jodrell Bank of the continuum radio emission from nearby galaxies. The objects include normal galaxies, Seyfert galaxies and others with nuclei active at optical and radio wavelengths.

Developing and adult reef fish show rapid light‐induced plasticity in their visual system
Molecular Ecology, Volume 32, Issue 1, Page 167-181, January 2023., 2023 Abstract The visual capabilities of fish are optimized for their ecology and light environment over evolutionary time. Similarly, fish vision can adapt to regular changes in light conditions within their lifetime, e.g., ontogenetic or seasonal variation.

Radio Continuum Surveys of the Galaxy and Galaxies [PDF]
Symposium - International Astronomical Union, 2002 Radio sky surveys give us basic information about the origin of the radio emission from the Galaxy. By mapping the sky at several radio frequencies a separation of the thermal and non-thermal emission components is possible. The major part of the low-frequency radio emission comes from the synchrotron process, the braking of relativistic electrons in ...

Radio continuum and CO emission in star-forming galaxies [PDF]
Astronomy & Astrophysics, 2002 We combine the radio continuum images from the NRAO VLA Sky Survey with the CO-line observations from the extragalactic CO survey of the Five College Radio Astronomy Observatory to study the relationship between molecular gas and the star formation rate within the disks of 180 spiral galaxies at 45" resolution. We find a tight correlation between these

Radio Continuum Emission in Polar Ring Galaxies
The Astronomical Journal, 2004 We have used the Very Large Array aperture synthesis telescope to conduct a radio continuum survey of polar-ring galaxies, at 20cm and 6cm. Forty objects were observed at 20cm with 5" resolution. Twenty (50%) of the program sources were detected at 20cm, down to our 5-sigma limit of 0.5 mJy/beam.

CO in the Bipolar Radio Continuum Galaxy NGC 3367 [PDF]
The Astronomical Journal, 2005 CO emission has been imaged at 2" resolution in the central 10 kpc of the barred spiral galaxy NGC 3367. This galaxy has bipolar synchrotron lobes out to a radii of 6 kpc, straddling the compact nucleus. The peak molecular emission is in a source of radius 2" (425 pc) centered on the galaxy nucleus.

Why radio quiet quasars are preferred over radio loud quasars regardless of environment and redshift [PDF]
The Astrophysical Journal 2020, 2020 Evidence has accumulated suggesting the clustering of radio loud quasars is greater than for radio quiet quasars. We interpret these results in a context in which the fraction of radio loud quasar formation is less than or equal to that for radio quiet quasars for all environments and redshift.
