Feasibility of up-the-ramp sampling under variable sky for ground-based spectrographs
Gaia Gaspar, Marcin Sawicki, Nelson Nunes +2
Many modern near-infrared instruments employ HAWAII-2RG (H2RG) detectors with integration times that can reach 300-600s. Up-the-ramp (UTR) sampling offers advantages over Fowler sa…
UV-to-optical insights into the BH model in little red dots
Rosa M. Mérida, Rosa M. Mérida, Marcin Sawicki +3
Little Red Dots (LRDs) are a heterogeneous class of objects, with several proposed scenarios for their physical nature and evolution. While these theories have been tested on indiv…
Testing the BH Model: a UV-to-Optical Spectral Fitting of The Cliff
Rosa M. Mérida, Marcin Sawicki, Gaia Gaspar +2
In the black hole star (BH*) model, the characteristic "V"-shaped SED of LRDs is produced by an accreting BH embedded in a dense neutral-gas envelope with a near-unity covering fac…
The rise and fall of Little Red Dots could be driven by the environment
Rosa M. Mérida, Gaia Gaspar, Yoshihisa Asada +9
The Little Red Dot (LRD) paradigm comprises three main unknowns that are intrinsically connected: (1) What is the nature of these sources? (2) How do they form? (3) How do they evo…
Probing the Star Formation Main Sequence down to 10 at
Rosa M. Mérida, Marcin Sawicki, Kartheik G. Iyer +12
The Main Sequence of Star-Forming Galaxies (SFGMS or MS) is a fundamental scaling relation that provides a global framework for studying galaxy formation and evolution, as well as…
A deep dive down the broad-line region: permitted OI, CaII and FeII emission in an AGN Little Red Dot at z=5.3
Roberta Tripodi, MaruÅ¡a BradaÄ, Francesco D'Eugenio +27
We present a spectroscopic analysis of a broad-line active galactic nucleus (AGN) selected as little red dot at behind the Bullet cluster (Bz5.3), based on JWST/NIRCam an…
