The atmospheric extinction of light
Stephen W. Hughes, Michael J. Cowley, Sean Powell +1
An experiment is described that enables students to understand the properties of atmospheric extinction due to Rayleigh scattering. The experiment requires the use of red, green an…
Satellite Quenching and Galactic Conformity at 0.3 < z < 2.5
Lalitwadee Kawinwanichakij, Ryan F. Quadri, Casey Papovich +21
We measure the evolution of the quiescent fraction and quenching efficiency of satellites around star-forming and quiescent central galaxies with stellar mass $\log(M_{\mathrm{cen}…
Radio galaxies in ZFOURGE/NMBS: no difference in the properties of massive galaxies with and without radio-AGN out to z = 2.25
G. A. Rees, L. R. Spitler, R. P. Norris +11
In order to reproduce the high-mass end of the galaxy mass-distribution, some process must be responsible for the suppression of star-formation in the most massive of galaxies. Com…
The SFR-M* Relation and Empirical Star-Formation Histories from ZFOURGE at 0.5 < z < 4
Adam R. Tomczak, Ryan F. Quadri, Kim-Vy H. Tran +19
We explore star-formation histories (SFHs) of galaxies based on the evolution of the star-formation rate stellar mass relation (SFR-M*). Using data from the FourStar Galaxy Evoluti…
Parallax in the park
Stephen Hughes, Sean Powell, Joshua Carroll +1
This article describes a parallax experiment performed by undergraduate physics students at Queensland University of Technology. The experiment is analogous to the parallax method…
Characterization of transiting exoplanets by way of differential photometry
Michael Cowley, Stephen Hughes
This paper describes a simple activity for plotting and characterizing the light curve from an exoplanet transit event by way of differential photometry analysis. Using free digita…
Z-FIRE: ISM properties of the z = 2.095 COSMOS Cluster
Lisa J. Kewley, Tiantian Yuan, Themiya Nanayakkara +9
We investigate the ISM properties of 13 star-forming galaxies within the z~2 COSMOS cluster. We show that the cluster members have [NII]/Ha and [OIII]/Hb emission-line ratios simil…
The sizes of massive quiescent and star forming galaxies at z~4 with ZFOURGE and CANDELS
Caroline M. S. Straatman, Ivo Labbe, Lee R. Spitler +17
We study the rest-frame ultra-violet sizes of massive (~0.8 x 10^11 M_Sun) galaxies at 3.4<z<4.2, selected from the FourStar Galaxy Evolution Survey (ZFOURGE), by fitting single Se…
The Differential Size Growth of Field and Cluster Galaxies at z=2.1 Using the ZFOURGE Survey
Rebecca J. Allen, Glenn G. Kacprzak, Lee R. Spitler +13
There is ongoing debate regarding the extent that environment affects galaxy size growth beyond z>1. To investigate the differences in star-forming and quiescent galaxy properties…
The Absence of an Environmental Dependence in the Mass-Metallicity Relation at z=2
Glenn G. Kacprzak, Tiantian Yuan, Themiya Nanayakkara +10
We investigate the environmental dependence of the mass-metallicity relation at z=2 with MOSFIRE/Keck as part of the ZFIRE survey. Here, we present the chemical abundance of a Virg…
