MSA-3D: Rotation Curves and Dark Matter Fractions at z~0.5-1.7 with JWST/NIRSpec

Juan M. Espejo Salcedo, Danail Obreschkow, Karl Glazebrook +17

We present rotation curves and inner mass distributions for 30 star-forming galaxies at , observed with JWST/NIRSpec as part of the MSA-3D Cycle 1 survey. Combining spat…

Hidden in Pixels I: Discovery of dual "little red dots" indicates excess clustering on kilo-parsec scales

Takumi S. Tanaka, John D. Silverman, Kazuhiro Shimasaku +56

``Little Red Dots'' (LRDs) are an abundant high-redshift population newly discovered by the James Webb Space Telescope (JWST) and considered to be an early growth phase of supermas…

Unveiling Extended Components of 'Little Red Dots' in Rest-Frame Optical

Yiyang Zhang, Xuheng Ding, Lilan Yang +26

Recent JWST observations have revealed a population of red, compact, high-redshift objects called 'Little Red Dots'(LRD), whose host components have remained largely unconstrained,…
