Kavli Affiliate: Roberto Maiolino | First 5 Authors: Amanda Stoffers, Amanda Stoffers, , , | Summary: Direct observations of Lyman continuum (LyC) radiation from galaxies during the Epoch of Reionization (EoR) are impeded by absorption in the intergalactic medium, requiring indirect methods to infer the escape fraction of ionizing photons ($f_rm esc^rm LyC$). One approach […]

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Michael Koss, Michael Koss, , , | Summary: The AXIS Community Science Book represents the collective effort of more than 500 scientists worldwide to define the transformative science enabled by the Advanced X-ray Imaging Satellite (AXIS), a next-generation X-ray mission selected by NASA’s Astrophysics Probe Program for […]

Kavli Affiliate: Debora Sijacki | First 5 Authors: Eun-jin Shin, Eun-jin Shin, , , | Summary: We present a suite of high-resolution simulations to study how different stellar feedback channels regulate the growth of central intermediate-mass black holes (IMBHs) in dwarf galaxies hosting nuclear star clusters (NSCs). We employ a super-Lagrangian refinement scheme to resolve […]

Kavli Affiliate: Roberto Maiolino | First 5 Authors: A. Lola Danhaive, A. Lola Danhaive, , , | Summary: JWST/NIRCam slitless spectroscopy enables dynamical mass measurements for typical star-forming galaxies only a billion years after the Big Bang. We model the H$alpha$ morpho-kinematics of 163 galaxies at redshift $zapprox4$-6 from FRESCO and CONGRESS (with JADES imaging), […]

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Dávid Puskás, Dávid Puskás, , , | Summary: Galaxy mergers and interactions are often invoked to explain enhanced star formation, black hole growth, and mass build-up of galaxies at later cosmic times, but their effect is poorly understood at high redshift ($z>2$). We use JADES data to […]

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Francesco D’Eugenio, Francesco D’Eugenio, , , | Summary: We present JWST/NIRSpec dense-shutter spectroscopy (DSS). This novel observing strategy with the NIRSpec micro-shutter assembly (MSA) deliberately permits a high number of controlled spectral overlaps to reach extreme multiplex while retaining the low background of slit spectroscopy. In a […]

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Greta Zucchi, Greta Zucchi, , , | Summary: Observations with the James Webb Space Telescope (JWST) have uncovered a substantial population of high-redshift, broad-line active galactic nuclei (AGNs), whose properties challenge standard models of black hole growth and AGN emission. We analyze a spectroscopic sample of 34 […]

Kavli Affiliate: Debora Sijacki | First 5 Authors: Martin G. H. Krause, Martin G. H. Krause, , , | Summary: We review the state of the evidence for the existence and observational appearance of supermassive black hole binaries. Such objects are expected from standard hierarchical galaxy evolution to form after two galaxies, each containing a […]

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Emma Curtis-Lake, Emma Curtis-Lake, , , | Summary: This paper accompanies Data Release 4 of the JWST Deep Extragalactic Survey (JADES), which presents the full NIRSpec spectroscopy of the survey. We provide spectra of 5190 targets across GOODS-North and GOODS-South (including the Hubble Ultra Deep Field), observed […]
