We present IRAM Plateau de Bure Interferometer 3 mm observations of CO J(1→0) emission in two 24μm-selected starburst galaxies in the outskirts (∼2–3Rvirial) of the rich cluster Cl 0024+16 (z = 0.395). The galaxies’ inferred far-infrared luminosities place them in the luminous infrared galaxy class (LIRGs, LFIR > 10L⊙), with star formation rates of ∼60M⊙ yr. Strong CO J(1→0) emission is detecte...

We present the results of the “Cosmogrid” cosmological N -body simulation suites based on the concordance LCDM model. The Cosmogrid simulation was performed in a 30Mpc box with 20483 particles. The mass of each particle is 1.28× 10M!, which is sufficient to resolve ultra-faint dwarfs. We found that the halo mass function shows good agreement with the Sheth & Tormen (1999) fitting function down ...

The first-generation stars in the ΛCDM universe are considered to have formed in dark halos with total masses in the range ∼ 10−10M⊙ at z ∼ 20−50. These stars expected to be very massive and in some cases they end their lives as the first supernovae (SNe). We explore the problem of whether star formation in low mass dark halos (6 10M⊙) was triggered or suppressed by the SN feedback from neighbo...

The Arecibo Legacy Fast ALFA (ALFALFA) survey is a program aimed at obtaining a census of HI-bearing objects over a cosmologically significant volume of the local universe. When complete in ∼3–4 years, it will cover 7000 square degrees of high latitude sky using the 305 m telescope and the seven-beam Arecibo L-band feed array (ALFA). As of May 1, 2008, almost 60% of the required observations ar...

We have obtained high-dispersion spectra for four massive star clusters in the dwarf irregular galaxies NGC 4214 and NGC 4449, using the HIRES spectrograph on the Keck I telescope. Combining the velocity dispersions of the clusters with structural parameters and photometry from images taken with the Hubble Space Telescope, we estimate mass-to-light ratios and compare these with simple stellar p...

Pulse radiolysis in chlorinated hydrocarbon liquids such as 1,2-dichloroethane is a versatile and effective method for the generation of solute radical cations. The addition of a large concentration of toluene or benzene to solutions of 1,2dichloroethane is found to increase the yield of solute radical cations (G=0.68molecules 100 eV 1 in 1,2-dichloroethane (J. Phys. Chem. 83(15) (1979) 1944) b...

The indentation behaviour of aluminium foams at low velocity (10m/s ∼ 30m/s) was investigated both in experiments and numerical simulation in this paper. A flat-ended indenter was used and the force-displacement history was recorded. The Split Hopkinson Pressure bar was used to obtain the indentation velocity and forces in the dynamic experiments. Because of the low strength of the aluminium fo...

The study aimed to compare the chronic eccentric-overload training effects of unilateral (lateral lunge) vs bilateral (half-squat) using an inertial device, on hypertrophy and physical performance. Twenty-seven young team sports male players performed a 4 sets of 7 repetitions of inertial eccentric overload training, biweekly for 6 weeks, distributed in unilateral lunge group (UG: age: 22.8 ± 2...

In large spheroidal stellar systems, such as elliptical galaxies, one invariably finds a 10-10M⊙ supermassive black hole at their centre. In contrast, within dwarf elliptical galaxies one predominantly observes a 10-10M⊙ nuclear star cluster. To date, few galaxies have been found with both type of nuclei coexisting and even less have had the masses determined for both central components. Here w...

The inspiral of binary black holes is governed by gravitational radiation reaction at binary separations r & 1000M, yet it is too computationally expensive to begin numerical-relativity simulations with initial separations r * 10M. Fortunately, binary evolution between these separations is well described by postNewtonian equations of motion. We examine how this post-Newtonian evolution affects ...
