Deep Space Network Radio Science and Ground‐Based Planetary Radar in the Next Decade
Radio Science, Volume 60, Issue 7, July 2025.Abstract The Deep Space Network (DSN) has been a core operational element of NASA's crewed and robotic exploration of the Solar System since the early 1960s. The primary role of the DSN has been to acquire telemetry and navigation data, but over the years, its radiometric and radar capabilities have expanded to form a system for obtaining unique ...

The X-ray flux from the warm-hot intergalactic medium
, 2007 In the past years significant efforts have been focused on describing the evolution and structure of the Universe. One of the big open questions in cosmology is "Where is the baryonic mass"?

Cosmic Reionization on Computers: The Evolution of the Ionizing Background and Mean Free Path
The Astrophysical JournalObservations of the end stages of reionization indicate that at z ≈ 5–6, the ionizing background is not uniform and the mean free path (MFP) changes drastically.

Simulations of the Intergalactic Medium [PDF]
Symposium - International Astronomical Union, 2005 I present an epochal review of baryons in the intergalactic medium (IGM), from the reionization epoch until today. Recent observations indicate a protracted period of reionization, suggesting multiple populations of reionizers; detection of these z ≳ 6 sources is a key goal that is now coming within reach.

The Astrophysical Journal LettersThe red damping wing from neutral hydrogen in the intergalactic medium is a key predicted signature of ongoing reionization. One potential contaminant of the intergalactic damping wing signal is dense gas associated with foreground galaxies, which can ...

Carbon Energy, Volume 7, Issue 2, February 2025.In this review, we aim to provide a comprehensive understanding of plasma and its application in energy storage and conversion. The classification of plasma technologies and principles are summarized. Recent developments in the synthesis or modification of multiscale materials based on plasma techniques including conversion, doping, deposition, and ...

The relationship between Gas and Galaxies [PDF]
, 2009 We have investigated the 2D 2-point correlation function, ƐAG, between low column density Lya absorbers and galaxies at a redshift z ~ 1 for the first time.

Strategy to Explore Magnetized Cosmic Web with Forthcoming Large Surveys of Rotation Measure
Galaxies, 2018 The warm-hot intergalactic medium (WHIM) is a candidate for the missing baryons in the Universe. If the WHIM is permeated with the intergalactic magnetic field (IGMF), the Faraday rotation measure (RM) of the WHIM is imprinted in linearly-polarized ...

The Journal of Popular Culture, Volume 57, Issue 3, Page 175-188, June 2024.Abstract Hulu's Prey (2022), the fifth installment of the Predator franchise, is set in 1719 and features a Comanche female protagonist. The setting is unlike the 1987 Predator and its sequels, with their hardbody machismo and conservative politics. We argue that Prey is a small but significant step in Hollywood, but its inclusivity comes at a price ...
