Beyond the Dot: an LRD-like nucleus at the Heart of an IR-Bright Galaxy and its implications for high-redshift LRDs

Pierluigi Rinaldi, George H. Rieke, Zihao Wu +23

Little Red Dots (LRDs) are compact, red sources discovered by JWST at high redshift (), marked by distinctive 'V-shaped' spectral energy distributions (SEDs) and often…

The galaxy UV luminosity function from the JWST Advanced Deep Extragalactic Survey: insights into early galaxy evolution and reionization

Lily Whitler, Daniel P. Stark, Michael W. Topping +24

The high-redshift UV luminosity function provides important insights into the evolution of early galaxies. JWST has revealed an unexpectedly large population of bright ($M_\mathrm{…

Little Red Dots: One Photometric Tag Concealing Diverse Spectroscopic Flavors of Massive Star Formation and Black Hole Activity

Pablo G. Pérez-González, Guillermo Barro, Stefano Carniani +62

We compile JWST/NIRSpec prism and MIRI data for 249 Little Red Dots (LRDs) at 2.3<z<9.3, forming a representative spectroscopic subset of NIRCam-selected LRDs. We derive a median s…

There Is More to Outshining: 2D Dust Effects on Stellar Mass Estimates at with JWST in the JADES Field

M. Hamed, P. G. Pérez-González, M. Annunziatella +15

Dust attenuation modifies the observed spectral energy distribution (SED), leading to biases in the properties inferred from integrated SED fitting. As spatially resolved SED model…

JADES: Rest-frame UV-to-NIR Size Evolution of Massive Quiescent Galaxies from Redshift z=5 to z=0.5

Zhiyuan Ji, Christina C. Williams, Katherine A. Suess +37

We present the UV-to-NIR size evolution of a sample of 161 quiescent galaxies (QGs) with over . With deep multi-band NIRCam images in GOODS-South from…

Galaxies in the Epoch of Reionization Are All Bark and No Bite -- Plenty of Ionizing Photons, Low Escape Fractions

Casey Papovich, Justin W. Cole, Weida Hu +27

Early results from JWST suggest that epoch-of-reionization (EoR) galaxies produce copious ionizing photons, which, if they escape efficiently, could cause reionization to occur too…
