Effects of magnetic fields on the kinetic inductance detector arrays for the terahertz intensity mapper

Talia Saeid, R. M. J. Janssen, Hessel Schulte, S. Hailey-Dunsheath et autres

Kinetic Inductance Detectors (KIDs) are superconducting micro-resonators used for radiation detection, with applications spanning astrophysics, cosmology, remote sensing, and quantum computing. Optimizing a KID array requires managing the internal quality factor (Qi) and minimizing frequency scatter: resonance frequency deviations of up to …

Resolved Dust in $z\approx1$ Galaxies with JWST/MIRI MRS: Survey Description and First View on PAHs, Mid-IR Atomic Emission, and Warm H$_2$

Wuji Wang, Andreas L. Faisst, Thomas S. -Y. Lai, Kyle Finner et autres

Dust is a key component of galaxies that regulates their thermal balance and, consequently, star formation and the build-up of stellar mass. Polycyclic aromatic hydrocarbons (PAHs) are responsible for reprocessing radiative energy of the galaxies thus tracing dust evolution. Using JWST/MIRI MRS, …

Tracing Lyman alpha escape in the CRISTAL-02 galaxy at z∼5.3

Arshi Ali, L. Guaita, Manuel Aravena, R. L. Davies et autres

Aim . We investigate the mechanisms regulating the escape of Lyman-alpha (Lẙm α) photons in the star-forming galaxy CRISTAL-02 at redshift z ≈ 5.3. Previous studies revealed a diffused and extended Lẙm α emitting gas (radius∼16.5 kpc) and a possible C, ii …

Widespread Extended [C II ] Emission in High-redshift Galaxies: Insights from the FIRE-2 Cosmological Zoom-in Simulations

Lun-Jun Liu, Guochao Sun, Andreas L. Faisst, Claude‐André Faucher‐Giguère et autres

Abstract Recent Atacama Large Millimeter/submillimeter Array observations reveal diffuse [C ii ] emission (“[C ii ] halos”) extending to ∼10 kpc in galaxies at 4 < z < 6. These measurements provide new insights into high-redshift galactic ecosystems and processes that drive …

Forecasting the Cross Correlation of Terahertz Intensity Mapper [C ii ] Line Intensity Maps with Euclid Galaxies

Justin S. Bracks, Ryan P. Keenan, Shubh Agrawal, Garrett K. Keating et autres

Abstract We forecast that the Terahertz Intensity Mapper (TIM) cross-correlated with Euclid’s Deep Field Fornax (EDF-F), TIM × EDF-F, will detect the [C ii ]-galaxy cross-power spectrum at a median redshift of 1.1 with ≳7 σ confidence. The Poisson component of the …

The ALPINE–CRISTAL–JWST Survey: The Fast Metal Enrichment of Massive Galaxies at z ∼ 5

Andreas L. Faisst, Lun-Jun Liu, Yohan Dubois, Yurina Nakazato et autres

Abstract We present the stellar mass–metallicity relation (MZR) and mass–metallicity–star formation relation (“fundamental metallicity relation”; FMR) of 18 massive ( log ( M ⋆ / M ⊙ ) = 9.5 − 11 ) main-sequence galaxies at z ∼ 5 from the ALPINE–CRISTAL–JWST …

The ALPINE-CRISTAL-JWST Survey: Chemical Abundance Comparison between the ISM and CGM of Main-sequence Galaxies at z = 4–6

Wuji 无忌 Wang 王, Andreas L. Faisst, Kyle Finner, Livia Vallini et autres

Abstract Gaseous halos around galaxies play an important role in galaxy evolution. The exchange of metals from the interstellar medium (ISM) to the circumgalactic medium (CGM) is caused by the formation, feedback, and/or merging history of galaxies. We study the variation in …

A New Window into the Baryon Cycle at Cosmic Noon with Line Intensity Mapping: Forecasts for auto- and cross-correlations in [CII]-158$μ$m, HI 21 cm, CO$_{J+1\rightarrow J}$, and H$α$ galaxies

Shubh Agrawal, James E. Aguirre, Justin S. Bracks, Ryan P. Keenan et autres

Across the peak of cosmic star formation at $z\sim1-2$, inflow, processing, and feedback drive rapid changes in the spatial distribution and chemical composition of baryons in galaxies and surrounding reservoirs; this baryon cycle can be tomographically mapped by line intensity mapping (LIM) …

Forecasting the cross correlation of Terahertz Intensity Mapper [CII] line intensity maps with Euclid galaxies

Justin S. Bracks, Ryan P. Keenan, Shubh Agrawal, Garrett K. Keating et autres

We forecast that the Terahertz Intensity Mapper (TIM) cross-correlated with Euclid's Fornax deep field (EDF-F), TIM$\times$EDF-F, will detect the [CII]-galaxy cross-power spectrum at a median redshift of 1.1 with $\gtrsim 7 σ$ confidence. The Poisson component of the cross-power spectrum at $0.1 …
