The <i>UV</i>–optical colour dependence of galaxy clustering in the local universe
Loh, Yeong-Shang,Rich, R. Michael,Heinis, Sé,bastien,Scranton, Ryan,Mallery, Ryan P.,Salim, Samir,Martin, D. Christopher,Wyder, Ted,Arnouts, Sté,phane,Barlow, Tom A.,Forster, Karl,Friedman Blackwell Publishing Ltd 2010 MONTHLY NOTICES- ROYAL ASTRONOMICAL SOCIETY Vol.407 No.1
<P>ABSTRACT</P><P>We measure the UV-optical colour dependence of galaxy clustering in the local Universe. Using the clean separation of the red and blue sequences made possible by the <I>NUV</I>−<I>r</I> colour–magnitude diagram, we segregate the galaxies into red, blue and intermediate ‘green’ classes. We explore the clustering as a function of this segregation by removing the dependence on luminosity and by excluding edge-on galaxies as a means of a non-model dependent veto of highly extincted galaxies. We find that ξ(<I>r</I><SUB>p</SUB>, π) for both red and green galaxies shows strong redshift-space distortion on small scales – the ‘finger-of-God’ effect, with green galaxies having a lower amplitude than is seen for the red sequence, and the blue sequence showing almost no distortion. On large scales, ξ(<I>r</I><SUB>p</SUB>, π) for all three samples show the effect of large-scale streaming from coherent infall. On scales of 1 <I>h</I><SUP>−1</SUP> Mpc < <I>r</I><SUB>p</SUB> < 10 <I>h</I><SUP>−1</SUP> Mpc, the projected auto-correlation function <I>w</I><SUB>p</SUB>(<I>r</I><SUB>p</SUB>) for red and green galaxies fits a power law with slope γ∼ 1.93 and amplitude <I>r</I><SUB>0</SUB>∼ 7.5 and 5.3, compared with γ∼ 1.75 and <I>r</I><SUB>0</SUB>∼ 3.9 <I>h</I><SUP>−1</SUP> Mpc for blue sequence galaxies. Compared to the clustering of a fiducial <I>L</I>* galaxy, the red, green and blue have a relative bias of 1.5, 1.1 and 0.9, respectively. The <I>w</I><SUB>p</SUB>(<I>r</I><SUB>p</SUB>) for blue galaxies display an increase in convexity at ∼ 1 <I>h</I><SUP>−1</SUP> Mpc, with an excess of large-scale clustering. Our results suggest that the majority of blue galaxies are likely central galaxies in less massive haloes, while red and green galaxies have larger satellite fractions, and preferentially reside in virialized structures. If blue sequence galaxies migrate to the red sequence via processes like mergers or quenching that take them through the green valley, such a transformation may be accompanied by a change in environment in addition to any change in luminosity and colour.</P>
TWISTED QUADRATIC MOMENTS FOR DIRICHLET L-FUNCTIONS
Stéphane R. Louboutin 대한수학회 2015 대한수학회보 Vol.52 No.6
Given c, a positive integer, we set M(f, c) := 2/Φ(f) ∑ χ∈X− f χ(c)|L(1, χ)|2, where X− f is the set of the Φ(f)/2 odd Dirichlet characters mod f > 2, with gcd(f, c) = 1. We point out several mistakes in recently published papers and we give explicit closed formulas for the f’s such that their prime divisors are all equal to ±1 modulo c. As a Corollary, we obtain closed formulas for M(f, c) for c 2 {1, 2, 3, 4, 5, 6, 8, 10}. We also discuss the case of twisted quadratic moments for primitive characters.

Determination of the orders generated by a cyclic cubic unit that are Galois invariant
Lee, Jun Ho,Louboutin, Sté,phane R. Elsevier 2015 Journal of number theory Vol.148 No.-
<P><B>Abstract</B></P> <P>Let <I>ϵ</I> be a totally real cubic algebraic unit. Assume that the cubic number field Q ( ϵ ) is Galois. In this situation, it is natural to ask when the cubic order Z [ ϵ ] is invariant under the action of the Galois group Gal ( Q ( ϵ ) / Q ) . It seems that this natural problem has never been looked at. We give an answer to this problem (e.g., we show that if <I>ϵ</I> is totally positive, then this happens in only 12 cases).</P>
Color and Brightness Tuning in Heteronuclear Lanthanide Terephthalate Coordination Polymers

<P><B>Abstract</B></P><P>Heteronuclear lanthanide terephthalate coordination polymers with the general chemical formula [Ln<SUB>2–2<I>x</I></SUB>Ln′<SUB>2<I>x</I></SUB>(bdc)<SUB>3</SUB>(H<SUB>2</SUB>O)<SUB>4</SUB>]<SUB>∞</SUB>, for which bdc<SUP>2–</SUP> symbolizes benzene‐1,4‐dicarboxylate (or terephthalate) and Ln and Ln′ represent trivalent rare earth ions, were synthesized and structurally characterized. Analysis of the Y/Lu compounds by <SUP>89</SUP>Y and <SUP>13</SUP>C solid‐state NMR spectroscopy was carried out, and the results support the hypothesis of randomly distributed lanthanide ions. The spectroscopic and colorimetric properties of this family of compounds were investigated in detail. The resulting data demonstrate that this series of compounds presents highly tunable luminescence properties and clearly indicate that intermetallic deactivation processes play an important role in the emission mechanism. Playing with intermetallic distances allows one to tune the color and the brightness of the lanthanide emission in these coordination polymers.</P>
