Stable isotope probing of magnetic-bead-captured rRNA (Mag-SIP) indicated clear differences in in situ organic substrate utilization by major microbial groups between the more oxidized (0 to 2 cm) and sulfate-reducing (2 to 5 cm) horizons of marine

Lead or Participate Guided Interest Groups (GIGs) are community learning experiences where students shepherd participants through the SC Technical Program. Participating students are expected to attend sessions planned by the GIG leaders as well as pre- and post-session discussions facilitated by the session lead. Once a student has registered and received a registration confirmation for ...

We present the history of investigation of the dynamical properties of pairs and groups of genetically related long-period comets (other than the Kreutz sungrazing system). Members of a comet pair or group move in nearly identical orbits and their origin as fragments of a common parent comet is unquestionable. The only variable is the time of perihelion passage, which differs from member to member considerably due primarily to an orbital-momentum increment acquired during breakup. Meter-per-second separation velocities account for gaps of years or tens of years, thanks to the orbital periods of many millennia. The physical properties of individual members may not at all be alike, as illustrated by the trio of C/1988 A1, C/1996 Q1, and C/2015 F3. We exploit orbital similarity to examine whether the celebrated and as yet unidentified object, discovered from the Lick Observatory near the Sun at sunset on 1921 August 7, happened to be a member of such a pair and to track down the long-period comet to which it could be genetically related. Our search shows that the Lick object, which could not be a Kreutz sungrazer, was most probably a companion to comet C/1847 C1 (Hind), whose perihelion distance was ~9 R_sun and true orbital period approximately 8300 years. The gap of 74.4 years between their perihelion times is consistent with a separation velocity of ~1 m/s that set the fragments apart following the parent's breakup in a general proximity of perihelion during the previous return to the Sun in the 7th millennium BCE.

Some local community groups gathered in north Killeen on Monday to be an outlet to residents.

We investigate the near-infrared K-band properties of the brightest cluster galaxies (BCGs) in a sample of 93 galaxy clusters and groups, using data from the Two Micron All Sky Survey. Our cluster sample spans a factor of 70 in mass, making it sensitive to cluster mass related trends. We study the correlations between the BCG luminosity L_b and the mass or luminosity of the host clusters, finding that BCGs in more massive clusters are more luminous than their counterparts in less massive systems, and that the BCGs become less important in the overall cluster light L200 as cluster mass increases. We argue that BCGs grow in luminosity mainly by merging with other luminous galaxies as the host clusters grow hierarchically; the decreasing BCG luminosity fraction L_b/L_200 with cluster mass indicates that the rate of luminosity growth in BCGs is slow compared to the rate at which clusters acquire galaxy light from the field or other merging clusters. We use the observed cluster luminosity-mass relation and a merger tree model to estimate that the amount of intracluster light (ICL) increases with cluster mass; calculations suggest that in 10^{15}Mo clusters more than 50% of total stellar mass is in ICL. The cluster baryon fraction accounting for the ICL is in good agreement with the CMB constraints. The inclusion of ICL reduces thediscrepancy between the observed cluster cold baryon fraction and that found in hydro simulations. Based on the observed Fe abundance in the ICM, we find that the predicted ICL together with the observed galaxy light, match the Fe mass-tolight ratio expected from simple stellar population models with a Salpeter IMF. The ICL also makes it easier to produce the Fe core excess found in cool-core clusters. (abridged)
