High-resolution radio imaging of TGSSJ1530+1049, a radio galaxy in a dense environment at z=4
K. Ã. Gabányi, S. Frey, L. I. Gurvits +10
High-redshift radio galaxies can provide insights into the structure formation and galaxy evolution at earlier cosmological epochs. TGSSJ1530+1049 was selected as a candidate high-…
JWST observes the assembly of a massive galaxy at z~4
Aayush Saxena, Roderik A. Overzier, Catarina Aydar +18
We present JWST observations of the radio galaxy TGSSJ1530+1049, spectroscopically confirmed at . NIRCam images and NIRSpec/IFU spectroscopy (R=2700) show that TGSSJ1530+104…
A Post-Starburst Pathway for the Formation of Massive Galaxies and Black Holes at z>6
Masafusa Onoue, Xuheng Ding, John D. Silverman +45
Understanding the rapid formation of supermassive black holes (SMBHs) in the early universe requires insight into stellar mass growth in host galaxies. Here, we present NIRSpec res…
Modelling the multi-wavelength detection of protoclusters. I: An excess of submillimetre galaxies in protocluster cores
Pablo Araya-Araya, Rachel K. Cochrane, Christopher C. Hayward +6
Studies of galaxy protoclusters yield insights into galaxy cluster formation complementary to those obtained via `archaeological' studies of present-day galaxy clusters. Submillime…
A quasar-galaxy merger at : rapid host growth via accretion of two massive satellite galaxies
Roberto Decarli, Federica Loiacono, Emanuele Paolo Farina +38
We present JWST/NIRSpec Integral Field Spectroscopy in the rest-frame optical bands of the system PJ308-21, a quasar at caught as its host galaxy interacts with companio…
