Deep space experiment to measure
Michael R. Feldman, John D. Anderson, Gerald Schubert +3
Responding to calls from the National Science Foundation (NSF) for new proposals to measure the gravitational constant , we offer an interesting experiment in deep space employi…
Astro2020 State of the Profession White Paper: Astronomy's Archival Materials
James Lattis, Wayne Osborn, Jennifer Lynn Bartlett +7
We argue that it is essential that the Astro2020 survey of the present state of American astronomy and the recommendations for the next decade address the issue of ensuring preserv…
Anybody but Hubble!
Virginia Trimble
The recent literature of astronomy and cosmology has included a good many suggestions for "who first recognized the expansion of the universe?" with cases having been made for Lema…
A citation history of measurements of Newtons constant of Gravity
Katelyn Horstman, Virginia Trimble
We created and analyzed a citation history of papers covering measurements of Newtons constant of gravity from 1686 to 2016. Interest concerning the true value of the gravitational…
An Overview of Seven Astronomical Decadal Surveys on Successes, Failures, and Shifting Demographics
Michelle Pan, Virginia Trimble
We take a fresh look at about 60 years of recommendations for US federal funding for astronomical and astrophysical facilities provided by seven survey committees at roughly 10-yea…
The Impact Of World War I On Relativity: Part III, The Aftermath
Virginia Trimble
Neither the world nor science came to an end when the gunfire stopped on 11 November 1918 (close to 11 AM in some time zone), but neither would ever be the same again. Part I of th…
Order out of Randomness : Self-Organization Processes in Astrophysics
Markus J. Aschwanden, Felix Scholkmann, William Bethune +13
Self-organization is a property of dissipative nonlinear processes that are governed by an internal driver and a positive feedback mechanism, which creates regular geometric and/or…
The quest for collapsed/frozen stars in single-line spectroscopic binary systems
Virginia Trimble
Black holes are now commonplace, among the stars, in Galactic centers, and perhaps other places. But within living memory, their very existence was doubted by many, and few chose t…
Science-Driven Optimization of the LSST Observing Strategy
LSST Science Collaboration, Phil Marshall, Timo Anguita +102
The Large Synoptic Survey Telescope is designed to provide an unprecedented optical imaging dataset that will support investigations of our Solar System, Galaxy and Universe, acros…
A Chandra Search for Coronal X Rays from the Cool White Dwarf GD 356
Martin C. Weisskopf, Kinwah Wu, Virginia Trimble +4
We report observations with the Chandra X-ray Observatory of the single, cool, magnetic white dwarf GD 356. For consistent comparison with other X-ray observations of single white…
Star Formation from Spitzer (Lyman) to Spitzer (Space Telescope) and Beyond
Joao Alves, Virginia Trimble
A summary of JENAM 2008 Symposium 9 "Star Formation from Spitzer (Lyman) to Spitzer (Space Telescope) and Beyond", held in Vienna, 10-12 September 2008.
Spectroscopic Binaries and Collapsed Stars: Part II
Virginia Trimble, Kip S. Thorne
Fifty years ago, borrowing an idea from our Russian friends Guseinov and Zeldovich, we looked for very compact stars (neutron stars and black holes, in modern terminology) as optic…
Interferometry meets the third and fourth dimensions in galaxies
Virginia Trimble
Radio astronomy began with one array (Jansky's) and one paraboloid of revolution (Reber's) as collecting areas and has now reached the point where a large number of facilities are…
Astrophysics in 2006
Virginia Trimble, Markus J. Aschwanden, Carl J. Hansen
The fastest pulsar and the slowest nova; the oldest galaxies and the youngest stars; the weirdest life forms and the commonest dwarfs; the highest energy particles and the lowest e…
Rubin Observatory LSST Transients and Variable Stars Roadmap
Kelly M. Hambleton, Federica B. Bianco, Rachel Street +79
The Vera C. Rubin Legacy Survey of Space and Time holds the potential to revolutionize time domain astrophysics, reaching completely unexplored areas of the Universe and mapping va…
The Impact of World War I on Relativity: A Progress Report
Virginia Trimble
From an astronomical and relativistic point of view, the Great War began with the August, 1914 capture and imprisonment of the members of a German eclipse expedition that had gone…
Cosmologists in the dark
Vicent J. Martinez, Virginia Trimble
We review the present status of cosmological discoveries and how these confirm our modern cosmological model, but at the same time we try to focus on its weaknesses and inconsisten…
Reply to comment by M. Pitkin on "Measurements of Newton's gravitational constant and the length of day"
John D. Anderson, Gerald Schubert, Virginia Trimble +1
We offer a response to recent claims that a constant measurement model with an additional Gaussian noise term fits the experimental data better than a model containing periodic…
Measurements of Newton's gravitational constant and the length of day
John D. Anderson, Gerald Schubert, Virginia Trimble +1
About a dozen measurements of Newton's gravitational constant, G, since 1962 have yielded values that differ by far more than their reported random plus systematic errors. We find…
Scaling Laws in the Distribution of Galaxies
Bernard J. T. Jones, Vicent J. Martinez, Enn Saar +1
Research done during the previous century established our Standard Cosmological Model. There are many details still to be filled in, but few would seriously doubt the basic premise…
My companion is bigger than your companion!
Henri M. J. Boffin, Virginia Trimble
We provide an analysis of the mass ratio distribution as gathered from almost all of the 559 orbital solutions derived by Professor Roger Griffin in his long series in the Observat…
LSST Science Book, Version 2.0
LSST Science Collaboration, Paul A. Abell, Julius Allison +245
A survey that can cover the sky in optical bands over wide fields to faint magnitudes with a fast cadence will enable many of the exciting science opportunities of the next decade.…
