, 1996 A characteristic spectrum of relic gravitational radiation is produced by a
period of ``stringy inflation" in the early universe. This spectrum is unusual,
because the energy-density rises rapidly with frequency. We show that

Astronomische Nachrichten, Volume 347, Issue 3, March 2026.ABSTRACT
Planetary nebulae represent a late evolutionary phase of low‐ to intermediate‐mass stars. In this article, we present the serendipitous discovery of a previously unknown, faint potential Galactic planetary nebula (PN) in the constellation Camelopardalis, identified during a survey‐inspection, aiming at the detection of dwarf companions of the ...W.

Physical Review D, 2010 Accumulation of electrical charge on the end mirrors of gravitational wave observatories, such as the space-based LISA mission and ground-based LIGO detectors, can become a source of noise limiting the sensitivity of such detectors through electronic couplings to nearby surfaces.Pollack, S.

Limnology and Oceanography Letters, Volume 11, Issue 2, March 2026.Abstract
Reservoirs are globally important sources of greenhouse gases, but the magnitude of their emissions is highly uncertain. Here, we present data for 146 reservoirs from two surveys of reservoir methane and carbon dioxide emissions, one at the regional scale in the midwestern United States and one at the national scale in the United States, plus ...J.

The Astrophysical Journal, 2007 The Laser Interferometer Gravitational-Wave Observatory (LIGO) has performed the fourth science run, S4, with significantly improved interferometer sensitivities with respect to previous runs. Using data acquired during this science run, we place a limit on the amplitude of a stochastic background of gravitational waves.Abbott, B., Abbott, R., Adhikari, R., Agresti, J., Ajith, P., Allen, B., Amin, R., Anderson, S.

Journal of Geophysical Research: Planets, Volume 131, Issue 3, March 2026.Abstract
Asteroid (16) Psyche, the largest member of the M/X‐type asteroids, may be the leftover core of a differentiated planetesimal. As such (16) Psyche will be explored in detail by NASA's discovery‐class Psyche mission in 2029. This will be the first mission to orbit a metal‐rich asteroid, or any asteroid in the 100–500 km size range.Namya Baijal, Erik Asphaug, C.
