Circumnuclear Medium around the Central AGN in a Cool-core Cluster, Abell 1644-South (2022)
Journal Article
Baek, J., Chung, A., Edge, A., Rose, T., Kim, J.-W., & Jung, T. (2022). Circumnuclear Medium around the Central AGN in a Cool-core Cluster, Abell 1644-South. Astrophysical Journal, 932(1), Article 64. https://doi.org/10.3847/1538-4357/ac6de6

We present the circumnuclear multiphase gas properties of the brightest cluster galaxy (BCG) in the center of Abell 1644-South (A1644-S). A1644-S is the main cluster in a merging system, which is well known for X-ray hot gas sloshing in its core. The...

Primordial Helium-3 Redux: The Helium Isotope Ratio of the Orion Nebula* (2022)
Journal Article
Cooke, R. J., Noterdaeme, P., Johnson, J. W., Pettini, M., Welsh, L., Peroux, C., Murphy, M. T., & Weinberg, D. H. (2022). Primordial Helium-3 Redux: The Helium Isotope Ratio of the Orion Nebula*. Astrophysical Journal, 932(1), Article 60. https://doi.org/10.3847/1538-4357/ac6503

We report the first direct measurement of the helium isotope ratio, 3He/4He, outside of the Local Interstellar Cloud, as part of science-verification observations with the upgraded CRyogenic InfraRed Echelle Spectrograph. Our determination of 3He/4He... Read More about Primordial Helium-3 Redux: The Helium Isotope Ratio of the Orion Nebula*.

FAST: Fourier domain adaptive optics simulation tool for bidirectional ground-space optical links through atmospheric turbulence (2022)
Journal Article
Farley, O., Townson, M., & Osborn, J. (2022). FAST: Fourier domain adaptive optics simulation tool for bidirectional ground-space optical links through atmospheric turbulence. Optics Express, 30(13), 23050-23064. https://doi.org/10.1364/oe.458659

Free space optical links between the ground and space may be severely degraded by atmospheric turbulence. Adaptive Optics, a technique allowing partial correction of this degradation, is beginning to see use in the field with the potential to achieve...

Microlensing and the type Ia supernova iPTF16geu (2022)
Journal Article
Diego, J., Bernstein, G., Chen, W., Goobar, A., Johansson, J., Kelly, P., Mörtsell, E., & Nightingale, J. (2022). Microlensing and the type Ia supernova iPTF16geu. Astronomy & Astrophysics, 662, Article A34. https://doi.org/10.1051/0004-6361/202143009

The observed magnifications and light curves of the quadruply imaged iPTF16geu supernova (SN) offers a unique opportunity to study a lens system with a variety of independent constraints. The four observed positions can be used to constrain the macro... Read More about Microlensing and the type Ia supernova iPTF16geu.

The Fornax3D project: intrinsic correlations between orbital properties and the stellar initial mass function (2022)
Journal Article
Poci, A., McDermid, R., Lyubenova, M., Martín-Navarro, I., van de Ven, G., Coccato, L., Corsini, E., Fahrion, K., Falcón-Barroso, J., Gadotti, D., Iodice, E., Pinna, F., Sarzi, M., de Zeeuw, P., & Zhu, L. (2022). The Fornax3D project: intrinsic correlations between orbital properties and the stellar initial mass function. Monthly Notices of the Royal Astronomical Society, 514(3), 3660-3669. https://doi.org/10.1093/mnras/stac1514

Variations of the stellar initial mass function (IMF) in external galaxies have been inferred from a variety of independent probes. Yet the physical conditions causing these variations remain largely unknown. In this work, we explore new spatially re...

A general framework to test gravity using galaxy clusters VI: Realistic galaxy formation simulations to study clusters in modified gravity (2022)
Journal Article
Mitchell, M. A., Arnold, C., & Li, B. (2022). A general framework to test gravity using galaxy clusters VI: Realistic galaxy formation simulations to study clusters in modified gravity. Monthly Notices of the Royal Astronomical Society, 514(3), 3349-3365. https://doi.org/10.1093/mnras/stac1528

We present a retuning of the IllustrisTNG baryonic physics model which can be used to run large-box realistic cosmological simulations with a lower resolution. This new model employs a lowered gas density threshold for star formation and reduced ener...

The In Situ Origins of Dwarf Stellar Outskirts in FIRE-2 (2022)
Journal Article
Kado-Fong, E., Sanderson, R. E., Greene, J. E., Cunningham, E. C., Wheeler, C., Chan, T., El-Badry, K., Hopkins, P. F., Wetzel, A., Boylan-Kolchin, M., Faucher-Giguère, C.-A., Huang, S., Quataert, E., & Starkenburg, T. (2022). The In Situ Origins of Dwarf Stellar Outskirts in FIRE-2. Astrophysical Journal, 931(2), Article 152. https://doi.org/10.3847/1538-4357/ac6c88

Extended, old, and round stellar halos appear to be ubiquitous around high-mass dwarf galaxies (108.5 < M⋆/M⊙ < 109.6) in the observed universe. However, it is unlikely that these dwarfs have undergone a sufficient number of minor mergers to form ste... Read More about The In Situ Origins of Dwarf Stellar Outskirts in FIRE-2.

Better magneto-optical filters with cascaded vapor cells (2022)
Journal Article
Logue, F. D., Briscoe, J. D., Pizzey, D., Wrathmall, S. A., & Hughes, I. G. (2022). Better magneto-optical filters with cascaded vapor cells. Optics Letters, 47(12), 2975-2978. https://doi.org/10.1364/ol.459291

Single-cell magneto-optical Faraday filters find great utility and are realized with either ‘wing’ or ‘line center’ spectral profiles. We show that cascading a second cell with independent axial (Faraday) or transverse (Voigt) magnetic field leads to... Read More about Better magneto-optical filters with cascaded vapor cells.

Modulated Fluorescence in LB Films Based on DADQs—A Potential Sensing Surface? (2022)
Journal Article

Novel fluorescent Langmuir-Blodgett (LB) films have been constructed from three different amphiphilic dicynaoquinodimethanes (DADQs). The DADQs varied in functional group structure, which had an impact on the LB film structure and the fluorescence pr...
