Astrophysics in 2005

Abstract

ABSTRACT. We bring you, as usual, the Sun and Moon and stars, plus some galaxies and a new section on astrobiology. Some highlights are short (the newly identified class of gamma-ray bursts, and the Deep Impact on Comet 9P/Tempel 1), some long (the age of the universe, which will be found to have the Earth at its center), and a few metonymic, for instance the term "down-sizing" to describe the evolution of star formation rates with redshift.

Usage bibliometrics

“…Kurtz, Eichhorn, Accomazzi, Grant, Demleitner, Murray, and colleagues (2005) pointed out that the series of papers by Trimble and colleagues: “Astrophysics in XXXX” (where XXXX is the immediate past year) each year is routinely the most used paper in astronomy, but is very rarely cited; for example, the most recent two, (Trimble, Aschwanden, & Hansen, 2006, 2007) have yet to be cited (as this is written). These papers are like newspapers in their usefulness.…”

Accelerated expansion from cosmological holography

“…2 shows our observational test of (11) and (7) with evolving, respectively, static dark energy in ΛCMD for a three-flat cosmology (Ade et al 2013), overlaid with the observed confidence region in the (q0, (dq/dz)0) plane obtained from the supernova survey of Riess et al (2004). The latter points to a deceleration parameter value about q0 ≃ −0.8 in the range −1 < q0 < −0.7 of John (2004) (see also Trimble et al (2006)). In this particular range of q0, Fig.…”

Astrophysics in 2006

“…Our low-frequency circle falls at 178 MHz and (the circled aspect) is old enough that it may well have originally been reported as pertaining to 178 Mc/s (Bridle 1967), with special thanks to Dwek and Barker (2005) for pointing out that this 40-year-old number is still the best available, 32 ± 8 K. And this is perhaps the least worst place to mention that the mostcycled author 60 has provided an overview of the discovery and interpretation of all the sorts of backgrounds she could think of (Trimble 2006).…”
