Several members of the department have kindly provided us with some pretty graphics illustrating aspects of their research or instructional work. Click on a thumbnail image to see a larger version. Enjoy!

Velocity field of the giant barred spiral galaxy NGC 1365, obtained with the Rutgers Fabry-Perot and the 1.5-meter telescope of the Cerro Tololo Interamerican Observatory. The colors represent velocities; due to the rotation of the galaxy, one side (shown in blue) is blueshifted relative to the center, while the other side is moving away, and redshifted (shown in red). Click here for an enlarged image. From a project of B. Weiner, T. Williams, and J. Sellwood.

Some of the longest exposures ever taken with the Hubble Space Telescope reveal faint white dwarfs in M4, the nearest globular cluster to earth. See the full image (160 K), the full caption, a press release, and a postscript image (480K) showing the color-magnitude diagram for the globular cluster stars. Contributed by C. Pryor.

Illustration of Medium Energy Ion Scattering (MEIS) from a TiO2 (110) surface. Contributed by D. Vanderbilt.

Scanning tunneling microscope (STM) images of surface faceting on W(111) induced by adsorption of ~1.6 atomic monolayers of Pd. Pyramids form spontaneously with {211} facets exposed. Contributed by C.-H. Nien and T.E. Madey.

Pattern of desorption of P atoms from PF3 molecules adsorbed on a metal surface. Contributed by T. Madey.

The polhode rolls without slipping on the herpolhode lying in the invariable plane! Click the image, or see here for an explanation and here for a neat movie (MPEG, 451K). Contributed by J. Shapiro.

Left: the forward detectors of the CDF experiment. Right: CDF event display showing fully reconstructed decay of a B meson to a J/psi and a K*.

Left: detailed view of reconstructed charged tracks near the event vertex of a top quark decay in CDF. Right: a spectacular top quark event, with an isolated electron (lower left), and four jets. Two of the jets come from b quarks, as evidenced by detached vertices reconstructed with the silicon microstrip vertex detector (SVX).

Several Rutgers physicists, including Profs. Plano and Kalelkar, are working on an experiment to make precision tests of the Standard Model by studying polarized electron-positron annihilations at the Stanford Linear Accelerator Center.

Left: Cutaway view of the SLD detector, which is 6 stories high and weighs 4000 tons!

Middle: Reconstructed event in the SLD detector. An electron-positron annihilation resulted in the creation of a quark, an antiquark, and a gluon, giving rise to the three jets of particles seen in the picture.

Right: A rare event in the SLD detector: quarks, antiquarks, and gluons from an electron-positron annihilation have fragmented into four jets of particles. The properties of such jets yield insights into the Standard Model.
