Complete IRAC mapping of the CFHTLS-DEEP, MUSYC AND NMBS-II FIELDS

Marianna Annunziatella, Danilo Marchesini, Mauro Stefanon +19

The IRAC mapping of the NMBS-II fields program is an imaging survey at 3.6 and 4.5 $μ$ m with the Spitzer Infrared Array Camera (IRAC). The observations cover three Canada-France-Haw…

Spatially Extended Low Ionization Emission Regions (LIERs) at $z \sim 0.9$

R. E. Hviding, G. B. Brammer, I. G. Momcheva +9

We present spatially resolved emission diagnostics for eight $z \sim 0.9$ galaxies that demonstrate extended low ionization emission-line regions (LIERs) over kpc scales. Eight candi…

HST F160W Imaging of Very Massive Galaxies at $1.5 < z < 3.0$ : Diversity of Structures and the Effect of Close Pairs on Number Density Estimates

Z. Cemile Marsan, Danilo Marchesini, Adam Muzzin +10

We present a targeted follow-up Hubble Space Telescope WFC3 F160W imaging study of very massive galaxies $(lo g (M_{star} / M_{⊙}) > 11.2)$ selected from a combination of grou…

A TESS Dress Rehearsal: Planetary Candidates and Variables from K2 Campaign 17

Ian J. M. Crossfield, Natalia Guerrero, Trevor David +38

We produce light curves for all ~34,000 targets observed with K2 in Campaign 17 (C17), identifying 34 planet candidates, 184 eclipsing binaries, and 222 other periodic variables. T…

Revealing the host galaxy of a quasar 2175 Å dust absorber at z = 2.12

Jingzhe Ma, Gabriel Brammer, Jian Ge +2

We report the first detection of the host galaxy of a strong 2175 Å dust absorber at z = 2.12 towards the background quasar SDSS J121143.42+083349.7 using HST/WFC3 IR F140W dire…

SDSS-IV MaNGA: The Spectroscopic Discovery of Strongly Lensed Galaxies

Michael S. Talbot, Joel R. Brownstein, Adam S. Bolton +11

We present a catalogue of 38 spectroscopically detected strong galaxy-galaxy gravitational lens candidates identified in the Sloan Digital Sky Survey IV (SDSS-IV). We were able to…

Planetary Candidates from K2 Campaign 16

Liang Yu, Ian J. M. Crossfield, Joshua E. Schlieder +20

Given that Campaign 16 of the K2 mission is one of just two K2 campaigns observed so far in "forward-facing" mode, which enables immediate follow-up observations from the ground, w…

Two warm, low-density sub-Jovian planets orbiting bright stars in K2 campaigns 13 and 14

Liang Yu, Joseph E. Rodriguez, Jason D. Eastman +25

We report the discovery of two planets transiting the bright stars HD 89345 (EPIC 248777106, $V = 9.376$ , $K = 7.721$ ) in K2 Campaign 14 and HD 286123 (EPIC 247098361, $V = 9.822$ , $K=8.…

SDSS-IV MaNGA: Stellar angular momentum of about 2300 galaxies: unveiling the bimodality of massive galaxy properties

Mark T. Graham, Michele Cappellari, Hongyu Li +14

We measure $λ_{R_{e}}$ , a proxy for galaxy specific stellar angular momentum within one effective radius, and the ellipticity, $ε$ , for about 2300 galaxies of all morphological types…

Unimodality of the independence polynomials of non-regular caterpillars

Patrick Bahls, Bailey Ethridge, Levente Szabo

The independence polynomial $I (G, x)$ of a graph $G$ is the polynomial in variable $x$ in which the coefficient $a_{n}$ on $x^{n}$ gives the number of independent subsets $S \subseteq…

The dependence of galaxy clustering on stellar mass, star-formation rate and redshift at z = 0.8-2.2, with HiZELS

R. K. Cochrane, P. N. Best, D. Sobral +3

The deep, near-infrared narrow-band survey HiZELS has yielded robust samples of H-alpha emitting star-forming galaxies within narrow redshift slices at z = 0.8, 1.47 and 2.23. In t…
