The trouble with STEAM and why we use it anyway
Science Education, Volume 105, Issue 2, Page 209-231, March 2021., 2021 Abstract As an emerging field of theory, research, and practice, STEAM (Science, Technology, Engineering, Arts, and Mathematics) has received attention for its efforts to incorporate the arts into the rubric of STEM (Science, Technology, Engineering, and Mathematics) learning.

Intergalactic star formation [PDF]
, 2006 Star formation in interacting systems may take place in various locations, from the dust--enshrouded core of Ultraluminous Infrared Galaxies to more unusual places such as the debris of colliding galaxies expelled into the intergalactic medium ...

On the Electromagnetic Vacuum Origins of Dark Energy, Dark Matter, and Astrophysical Jets
Advances in High Energy Physics, Volume 2021, Issue 1, 2021., 2021 We use a semiclassical version of the Nexus paradigm of quantum gravity in which the quantum vacuum at large scales is dominated by the second quantized electromagnetic field to demonstrate that a virtual photon field can affect the geometric evolution of Einstein manifolds or Ricci solitons.

The Intergalactic Medium [PDF]
Symposium - International Astronomical Union, 1982 The density of intergalactic gas may be an important parameter in the formation of extended radio sources. It may range from ∼ 0.1 particle cm−3 in the centres of some rich clusters of galaxies down to 10−8cm−3 or less in intercluster space. The possible influence of the intracluster gas surrounding NGC 1275 on its radio emission is discussed, and the ...

Dipole distortions in the intergalactic medium [PDF]
Monthly Notices of the Royal Astronomical Society, 2019 Abstract Baryonic feedback can significantly modify the spatial distribution of matter on small scales and create a bulk relative velocity between the dominant cold dark matter and the hot gas. We study the consequences of such bulk motions using two high-resolution hydrodynamic simulations, one with no feedback and one with very strong ...

A High-Resolution Study of the High-Redshift Intergalactic Medium [PDF]
, 2007 We present a study of the structure and evolution of the high-redshift intergalactic medium (IGM) using a variety of approaches based on high-resolution quasar spectra.

The Low-redshift Intergalactic Medium [PDF]
Publications of the Astronomical Society of Australia, 1999 AbstractThe low-redshift Lyα forest of absorption lines provides a probe of large-scale baryonic structures in the intergalactic medium, some of which may be remnants of physical conditions set up during the epoch of galaxy formation. We discuss our recent Hubble Space Telescope (HST) observations and interpretation of low-z Lyα clouds toward nearby ...

Microquasars as heating sources of the intergalactic medium during reionization of the Universe [PDF]
, 2017 International audienceThe effect of the primeval sources of radiation and particles on the thermodynamical state of the intergalactic medium during the epoch of reionization is still unclear.
