Detailed study of a rare hyperluminous rotating disk in an Einstein ring 10 billion years ago
Cresci, Giovanni; Frye, Brenda L.; Yun, Min S. +83 more
Hyperluminous infrared galaxies (HyLIRGs) are the rarest and most extreme starbursts and found only in the distant Universe (z ≳ 1). They have intrinsic infrared (IR) luminosities LIR ≥ 1013 L⊙ and are commonly found to be major mergers. Recently, the Planck All-Sky Survey to Analyze Gravitationally-lensed Extreme …
Observation of the Mars O2 visible nightglow by the NOMAD spectrometer onboard the Trace Gas Orbiter
Vandaele, A. C.; Daerden, F.; Thomas, I. R. +9 more
On Mars, atomic oxygen controls the carbon dioxide radiative cooling of the upper atmosphere and the presence of an ozone layer near the poles. To remotely probe meridional transport of O atoms from the summer to the winter hemisphere and the descending flow in the winter polar regions, the O2 Herzberg II atmospheric emission could be u…
A unified framework for global auroral morphologies of different planets
Merkin, V. G.; Lyon, J. G.; Delamere, P. A. +8 more
Planetary magnetic fields control energetic particles in their space environments and guide particles to polar atmospheres, where they produce stunning auroral forms. As revealed by spacecraft measurements of the Earth, Saturn and Jupiter, the pathways of energetic particles to these planetary polar atmospheres are diverse, suggesting that there a…
BepiColombo observations of cold oxygen and carbon ions in the flank of the induced magnetosphere of Venus
André, N.; Fedorov, A.; Krupp, N. +25 more
On 10 August 2021, the Mercury-bound BepiColombo spacecraft performed its second fly-by of Venus and provided a short-lived observation of its induced magnetosphere. Here we report results recorded by the Mass Spectrum Analyzer on board Mio, which reveal the presence of cold O+ and C+ with an average total flux of ~4 ± 1 × 10…
Diverse volcanism and crustal recycling on early Mars
Xiao, Long; Edwards, Christopher S.; Michalski, Joseph R. +2 more
The relatively well-preserved ancient crust of Mars provides a natural window into early planetary evolution not available on Earth due to sustained tectonic recycling and erosion on this planet. Mars has generally been considered a one-plate basaltic planet, though recent evidence suggests magmatic evolution resulting in felsic crust might have o…
The emerging archaeological record of Mars
Fairén, Alberto G.; Holcomb, Justin A.; O'Leary, Beth L. +2 more
Humans first reached Mars in 1971, initiating the record of human activity on the Red Planet. As planetary scientists plan for future planetary protection procedures for Mars, they should also consider the developing archaeological record on one of our nearest planets.
The X-ray mysteries of neutron stars and white dwarfs
Rea, Nanda; Schartel, Norbert
These two types of compact objects share several similarities, despite their different compositions. A short workshop in Spain brought communities together to share understanding of dense matter under extreme conditions.
