NL#140 May/June
May/June 2008 Issue 140 A Publication for the members of the American Astronomical President’s Column 5 J. Craig Wheeler, [email protected] Astrozone and K12 Educator Two interesting years go by very rapidly. This is my last newsletter article as President. Reception My thanks to all of you who have commented positively on them for your support and to those of you who did not feel so moved on your discretion. 6-9 My term ends with a bang rather than a whimper with the sudden resignation of Alan Stern and Scenes from the the return to the NASA Science Mission Directorate of old hand Ed Weiler. Reading between the lines, my take on this transition is that Alan was dedicated to doing more with a fixed Austin Meeting budget. An important boundary condition is that he could not allow cost growth in missions. His approach to this was one of tough love. He intended to first say “no.” Any mission with 17 a threat of overrun had to find its own way of solving that problem by downscoping or delay. If, in especially pressing circumstances, the damage could not be contained in the mission, Honored Alan intended to keep it in the division. No bleeding of planetary problems into astrophysics, Elsewhere nor vice versa. I think what happened is that Alan foresaw overruns coming down the pike for which various pressures beyond his control would not allow him to exercise this tough love. It was thus a matter of principle for him to resign. He did so, by his own statement, with 19 respect for the NASA Administrator and for the team he had assembled.

LIGHTING UP THE DARK: WHERE IS THE DARK MATTER? Neta A. Bahcall Princeton University 4:30 p.m., Tuesday, Nov. 11, 2014 Rashid Auditorium Gates & Hillman Centers Neta Bahcall uses different methods and a variety of tracers including galaxies, clusters of galaxies, Free and open to the public superclusters and quasars to answer fundamental questions about the structure of the universe. In Reception to follow work summarized in over 300 scientific publications, Bahcall and her colleagues have provided powerful How is dark matter distributed in the universe? How does it relate to the distribution of light, constraints on cosmology including one of the first stars and baryons? These questions are examined using gravitational lensing and other recent determinations of the mass-density of the universe and observations that trace the distribution of mass in the universe from small to large scales and of the amplitude of mass-fluctuations. reveal the connection between the dark and bright side of the universe. Born in Israel, Bahcall received her Ph.D. from While the halos of dark matter around galaxies show an observed mass distribution that is Tel Aviv University. She later moved to Princeton considerably more extended than that of light, this trend changes on larger scales, where the University where she is now the Eugene Higgins mass, light and stars trace each other remarkably well. This indicates the ‘edge’ of the dark matter Professor of Astrophysics. In her research, Bahcall distribution. The measurements suggest that most of the dark matter in the universe may be works closely with students and postdoctoral fellows.

The Scaling Relations of Galaxy Clusters and Their Dark Matter Halos
THE SCALING RELATIONS OF GALAXY CLUSTERS AND THEIR DARK MATTER HALOS B. Lanzoni1, L. Ciotti2,3, A. Cappi1, G. Tormen4, G. Zamorani1 1INAF – Osservatorio Astronomico di Bologna, via Ranzani 1, 40127, Bologna, Italy 2 Dipartimento di Astronomia, Universitàdi Bologna, via Ranzani 1, 40127 Bologna, Italy 3 Scuola Normale Superiore, Piazza dei Cavalieri 7, 56126 , Pisa, Italy 4 Dipartimento di Astronomia, Universitàdi Padova, vicolo dell’Osservatorio 5, 35122 Padova, Italy September 19, 2003; accepted ABSTRACT Like early-type galaxies, also nearby galaxy clusters define a Fundamental Plane, a luminosity- radius, and a luminosity-velocity dispersion relations, whose physical origin is still unclear. By means of high resolution N–body simulations of massive dark matter halos in a ΛCDM cosmology, we find that scaling relations similar to those observed for galaxy clusters are already defined by their dark matter hosts. The slopes however are not the same, and among the various possibilities in principle able to bring the simulated and the observed scaling relations in mutual agreement, we show that the preferred solution is a luminosity dependent mass-to-light ratio (M/L ∝ L∼0.3), that well corresponds to what inferred observationally. We then show that at galactic scales there is a conflict between the cosmological predictions of structure formation, the observed trend of the mass-to-light ratio in ellipticals, and the slope of their luminosity-velocity dispersion relation (that significantly differs from the analogous one followed by clusters). The conclusion is that the scaling laws of elliptical galaxies might be the combined result of the cosmological collapse of density fluctuations at the epoch when galactic scales became non-linear, plus important modifications afterward due to early-time dissipative merging.

Dark Matter Possibilities
Dark Matter Possibilities We now delve into possible explanations for this dark matter problem. Two readings on explanations for Dark Matter: 1. "Miraculous WIMPs", by Manuel Gnida, Symmetry Magazine, July 2015. https://www.symmetrymagazine.org/article/july-2015/miraculous-wimps 2. "Existence and Nature of Dark Matter in the Universe," Virginia Trimble, Ann. Rev. Astron. Astrophys. 25, 452-72 (1987). Section 1 (pp. 425-7) and Sections 6 and 7 (pp. 452-62). The full article and references are on the course web site. Artwork by Sandbox Studio, Chicago with Ana Kova Miraculous 07/15/15 | By Manuel Gnida What are WIMPs, and what makes WIMPs them such popular dark matter candidates? Invisible dark matter accounts for 85 percent of all matter in the universe, aLecting the motion of galaxies, bending the path of light and inuencing the structure of the entire cosmos. Yet we don’t know much for certain about its nature. Most dark matter experiments are searching for a type of particles called WIMPs, or weakly interacting massive particles. “Weakly interacting” means that WIMPs barely ever “talk” to regular matter. They don’t often bump into other matter and also don’t emit light—properties that could explain why researchers haven’t been able to detect them yet. Created in the early universe, they would be heavy (“massive”) and slow-moving enough to gravitationally clump together and form structures observed in today’s universe. Scientists predict that dark matter is made of particles. But that assumption is based on what they know about the nature of regular matter, which makes up only about 4 percent of the universe.
