Confirmation of Small Dynamical and Stellar Masses for Extreme Emission Line Galaxies at z~2
Michael V. Maseda, Arjen van der Wel, Elisabete da Cunha +21
Spectroscopic observations from the Large Binocular Telescope and the Very Large Telescope reveal kinematically narrow lines (~50 km/s) for a sample of 14 Extreme Emission Line Gal…
Clues to the Formation of Lenticular Galaxies Using Spectroscopic Bulge-Disk Decomposition
Evelyn J. Johnston, Alfonso Aragon-Salamanca, Michael R. Merrifield +1
Lenticular galaxies have long been thought of as evolved spirals, but the processes involved to quench the star formation are still unclear. By studying the individual star formati…
The number of cosmic string loops
Jose J. Blanco-Pillado, Ken D. Olum, Benjamin Shlaer
Using recent simulation results, we provide the mass and speed spectrum of cosmic string loops. This is the quantity of primary interest for many phenomenological signatures of cos…
Low Masses and High Redshifts: The Evolution of the Mass-Metallicity Relation
Alaina Henry, Claudia Scarlata, Alberto Dominguez +15
We present the first robust measurement of the high redshift mass-metallicity (MZ) relation at 10^{8}< M/M_{\sun} < 10^{10}, obtained by stacking spectra of 83 emission-line galaxi…
HST/WFC3 Near-Infrared spectroscopy of quenched galaxies at z~1.5 from the WISP Survey: Stellar population properties
A. G. Bedregal, C. Scarlata, A. L. Henry +15
We combine Hubble Space Telescope (HST) G102 & G141 NIR grism spectroscopy with HST/WFC3-UVIS, HST/WFC3-IR and Spitzer/IRAC[3.6μm] photometry to assemble a sample of massive (log(M…
A viable explanation of the CMB dipolar statistical anisotropy
Sugumi Kanno, Misao Sasaki, Takahiro Tanaka
The presence of a dipolar statistical anisotropy in the spectrum of cosmic microwave background (CMB) fluctuations was reported by the Wilkinson Microwave Anisotropy Probe (WMAP),…
