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…

astro-ph.GA2024

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…
