    Evolution Characteristics of Microbial Diversity During the Treatment of Black-odor Water by Carbon Fiber Bio-contact Oxidation by ZHANG Min, LIU Fengru, YIN Juan, LI Hongju, XU Yang, ZHANG Yang

    Published 2020-01-01
    “…In order to investigate the influence of the growth environment on the evolution of the structural diversity characteristics of the bacterial community during the treatment of black-odor water by carbon fiber bio-contact oxidation,this paper studies the characteristics of bacterial community on inoculated sludge,in-equipment activated sludge and carbon fiber membrane by high-throughput sequencing techniques.The results show that with the progress of biofilm culturing,the microbial species of activated sludge in the equipment gradually decreased,the diversity of bacterial community structure increased compared with inoculated sludge.The difference in bacterial community structure between the carbon fiber membrane D sample and E sample at stable phase was small.The analysis results of dominant bacterial flora show that there were 20 phylum found in the samples.The dominant microbial populations were Proteobacteria,Pachyphyta,Actinomycetes and Bacteroides with their relative abundance of about 75%~95%.At the class level,more than 20 classes were found in the samples,the dominant microbial populations were Alphaproteobacteria,Betaproteobacteria,Deltaproteobacteria and Gammaproteobacteria.The Alphaproteobacteria and Gammaproteobacteria on activated sludge and carbon fiber in the equipment were higher than those in the inoculated sludge,and the clostridia was lower than that in the inoculated sludge,indicating that the bacterial community structure had undergone significant changes after inoculated biofilm culturing with activated sludge.…”

    Galaxy evolution in the post-merger regime. III -- The triggering of active galactic nuclei peaks immediately after coalescence by Sara Ellison, Leonardo Ferreira, Robert Bickley, Tess Grindlay, Samir Salim, Shoshannah Byrne-Mamahit, Shobita Satyapal, David R. Patton, Jillian M. Scudder

    Published 2025-02-01
    “…Our main results are: 1) Regardless of the metric used, we find that the peak AGN excess (compared with a matched control sample) occurs immediately after coalescence, at 0 < T_PM < 0.16 Gyr. 2) The excess of AGN is observed until long after coalescence; both the mid-IR selected AGN and broad line AGN are more common than in the control sample even in the longest time bin of our sample (0.96 < T_PM < 1.76 Gyr). 3) The AGN excess is larger for more luminous and bolometrically dominant AGN, and we find that AGN in post-mergers are generally more luminous than secularly triggered events. 4) A deficit of broad line AGN in the pre-merger phase, that evolves into an excess in post-mergers is consistent with evolution of the covering fraction of nuclear obscuring material. …”
