A quasi-star is born: formation and evolution of accreting quasi-stars as a pathway to Little Red Dots at non-zero metallicity
J. Roman-Garza, D. Schaerer, C. Charbonnel +5
The recently discovered Little Red Dots identified by the James Webb Space Telescope are compact high-redshift sources whose properties have motivated models involving black holes…
Discovery of new N-emitters over a wide redshift range
I. Morel, D. Schaerer, R. Marques-Chaves +5
JWST observations have revealed rare galaxies with UV spectra exhibiting intense lines of nitrogen, indicative of super-solar N/O abundances at low metallicity. To better understan…
Unveiling dust, molecular gas, and high star formation efficiency in extremely UV bright star-forming galaxies at
M. Dessauges-Zavadsky, R. Marques-Chaves, D. Schaerer +4
We analysed ALMA FIR (1.3 mm) dust continuum and CO emission of 12 starburst galaxies at , selected for their extreme brightness in the rest-UV with $M_{\rm UV} = -2…
JWST FRESCO: a comprehensive census of H+[OIII] emitters at 6.8<z<9.0 in the GOODS fields
R. A. Meyer, P. A. Oesch, E. Giovinazzo +27
We present the census of H+[OIII] 4960,5008 Ã emitters at 6.8<z<9.0 from the JWST FRESCO survey over 124 arcmin in the GOODS-North and GOODS-South fields. Our unbiased spec…
