Odd Galaxy Couple on Space Voyage

07.09.2012
Two very different galaxies drift through space together in this image taken by NASA's Hubble Space Telescope. The peculiar galaxy pair is called Arp 116.

Arp 116 is composed of a giant elliptical galaxy known as Messier 60 (or M60) and a much smaller spiral galaxy, NGC 4647.

M60 is the third brightest galaxy in the Virgo cluster of galaxies, a collection of more than 1,300 galaxies. M60 has a diameter of 120,000 light-years and a mass of about one trillion times that of the Sun. A huge black hole of 4.5 billion solar masses lies at its center, one of the most massive black holes ever found.

The faint bluish spiral galaxy NGC 4647 is about two-thirds of M60 in size and much lower in mass -- roughly the size of our galaxy, the Milky Way.

Astronomers have long tried to determine whether these two galaxies are actually interacting. Although looking at them from Earth they overlap, there is no evidence of new star formation, which would be one of the clearest signs that the two galaxies are indeed interacting. However, recent studies of very detailed Hubble images suggest the onset of some tidal interaction between the two.

M60 lies roughly 54 million light-years away from Earth; NGC 4647 is about 63 million light-years away.

This image combines exposures from Hubble's Advanced Camera for Surveys and Wide Field and Planetary Camera 2.

Im Focus: Attoseconds break into atomic interior

A newly developed laser technology has enabled physicists in the Laboratory for Attosecond Physics (jointly run by LMU Munich and the Max Planck Institute of Quantum Optics) to generate attosecond bursts of high-energy photons of unprecedented intensity. This has made it possible to observe the interaction of multiple photons in a single such pulse with electrons in the inner orbital shell of an atom.

In order to observe the ultrafast electron motion in the inner shells of atoms with short light pulses, the pulses must not only be ultrashort, but very...

Im Focus: Good vibrations feel the force

A group of researchers led by Andrea Cavalleri at the Max Planck Institute for Structure and Dynamics of Matter (MPSD) in Hamburg has demonstrated a new method enabling precise measurements of the interatomic forces that hold crystalline solids together. The paper Probing the Interatomic Potential of Solids by Strong-Field Nonlinear Phononics, published online in Nature, explains how a terahertz-frequency laser pulse can drive very large deformations of the crystal.

By measuring the highly unusual atomic trajectories under extreme electromagnetic transients, the MPSD group could reconstruct how rigid the atomic bonds are...

Im Focus: In best circles: First integrated circuit from self-assembled polymer

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.

In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...
