The warm outer layer of a Little Red Dot as the source of [Fe II] and collisional Balmer lines with scattering wings
Alberto Torralba, Jorryt Matthee, Gabriele Pezzulli +22
The population of the Little Red Dots (LRDs) may represent a key phase of supermassive black hole (SMBH) growth. A cocoon of dense excited gas is emerging as key component to expla…
The slope and scatter of the star forming main sequence at z~5 : reconciling observations with simulations
Claudia Di Cesare, Jorryt Matthee, Rohan P. Naidu +17
Galaxies exhibit a tight correlation between their star-formation rate and stellar mass over a wide redshift range known as the star-forming main sequence (SFMS). With JWST, we can…
Rapid, out of equilibrium metal enrichment indicated by a flat mass-metallicity relation at z~6 from NIRCam grism spectroscopy
Gauri Kotiwale, Jorryt Matthee, Daichi Kashino +17
We aim to characterise the mass-metallicity relation (MZR) and the 3D correlation between stellar mass, metallicity and star-formation rate (SFR) known as the fundamental metallici…
A weak Ly halo for an extremely bright Little Red Dot: Indications of enshrouded SMBH growth
Alberto Torralba, Jorryt Matthee, Gabriele Pezzulli +13
The abundant population of "Little Red Dots" (LRDs)-compact objects with red UV to optical colors and broad Balmer lines at high redshift-is unveiling new insights into the propert…
Circumstellar interaction in the extreme white dwarf merger remnant ZTF\,J1901+1458: A new class of white dwarf merger remnants with X-ray emission
Aayush Desai, Ilaria Caiazzo, Stephane Vennes +31
Double degenerate white dwarf (WD) mergers can exhibit extreme magnetic fields exceeding G and rapid rotation, but their spectral-energy distributions and high-energy emis…
Environmental Evidence for Overly Massive Black Holes in Low Mass Galaxies and a Black Hole - Halo Mass Relation at
Jorryt Matthee, Rohan P. Naidu, Gauri Kotiwale +14
JWST observations have unveiled faint active galactic nuclei (AGN) at high-redshift that provide insights on the formation of supermassive black holes (SMBHs) and their coevolution…
