Feedback and ionized gas outflows in four low-radio power AGN at z 0.15
L. Ulivi, G. Venturi, G. Cresci +19
An increasing number of observations and simulations suggests that low-power (<10 erg s) jets may be a significant channel of feedback produced by active galactic nuc…
The Apache Point Observatory Galactic Evolution Experiment (APOGEE) Spectrographs
J. C. Wilson, F. R. Hearty, M. F. Skrutskie +86
We describe the design and performance of the near-infrared (1.51--1.70 micron), fiber-fed, multi-object (300 fibers), high resolution (R = lambda/delta lambda ~ 22,500) spectrogra…
At the end of cosmic noon: Short gas depletion times in unobscured quasars at 1
M. Frias Castillo, M. Rybak, J. Hodge +8
Unobscured quasars (QSOs) are predicted to be the final stage in the evolutionary sequence from gas-rich mergers to gas-depleted, quenched galaxies. Studies of this population, how…
Production and installation of wavelength-shifting reflective light enhancers for the Short-Baseline Near Detector
R. Acciarri, L. Aliaga-Soplin, R. Alvarez-Garrote +194
We report on the design, production, and installation of a wavelength-shifting reflective system on the cathode of the Short-Baseline Near Detector (SBND), a liquid argon time proj…
A Laterally Modulated 2D Electron System in the Extreme Quantum Limit
Sorin Melinte, Mona Berciu, C. Zhou +9
We report on magnetotransport of a two-dimensional electron system (2DES), located 32 nm below the surface, with a surface superlattice gate structure of periodicity 39 nm imposing…
The Spitzer mid-infrared AGN survey. I - optical and near-infrared spectroscopy of candidate obscured and normal AGN selected in the mid-infrared
M. Lacy, S. E. Ridgway, E. L. Gates +8
We present the results of a program of optical and near-infrared spectroscopic follow-up of candidate Active Galactic Nuclei (AGN) selected in the mid-infrared. This survey selects…
Spatially Resolved Spectroscopy of the E+A Galaxies in the z=0.32 Cluster AC114
M. B. Pracy, W. J. Couch, C. Blake +5
We present spatially resolved intermediate resolution spectroscopy of a sample of twelve E+A galaxies in the z=0.32 rich galaxy cluster AC 114, obtained with the FLAMES multi-integ…
SUPER. VI. A giant molecular halo around a z~2 quasar
C. Cicone, V. Mainieri, C. Circosta +16
We present the discovery of copious molecular gas in the halo of cid_346, a quasar studied as part of the SINFONI survey for Unveiling the Physics and Effect of Radiative f…
Probing the origin of low-frequency radio emission in PG quasars with the uGMRT -- I
Silpa S., P. Kharb, L. C. Ho +3
We present the results from 685 MHz observations with the upgraded Giant Metrewave Radio Telescope (uGMRT) of 22 quasars belonging to the Palomar-Green (PG) quasar sample. Only fou…
Investigating Differences in the Palomar-Green Blazar Population Using Polarization
Janhavi Baghel, P. Kharb, T. Hovatta +5
We present polarization images with the Karl G. Jansky Very Large Array (VLA) in A and B-array configurations at 6 GHz of 7 radio-loud (RL) quasars and 8 BL Lac objects belonging t…
High pressure study of BaFe2As2 - role of hydrostaticity and uniaxial stress
W. J. Duncan, O. P. Welzel, C. Harrison +4
We investigate the evolution of the electrical resistivity of BaFe2As2 single crystals with pressure. The samples used were from the same batch grown from self flux and showed prop…
