On the Viability of Determining Galaxy Properties from Observations I: Star Formation Rates and Kinematics

Kearn Grisdale, Laurence Hogan, Dimitra Rigopoulou +8

We explore how observations relate to the physical properties of the emitting galaxies by post-processing a pair of merging galaxies from the cosmological, hydrodynamical…

Predicting the Observability of Population III Stars with ELT-HARMONI via the Helium emission line

Kearn Grisdale, Niranjan Thatte, Julien Devriendt +5

Population III (Pop. III) stars, as of yet, have not been detected, however as we move into the era of extremely large telescopes this is likely to change. One likely tracer for Po…

Physical Properties and Scaling Relations of Molecular Clouds: the Impact of Star Formation

Kearn Grisdale

Using hydrodynamical simulations of a Milky Way-like galaxy, reaching 4.6 pc resolution, we study how the choice of star formation criteria impacts both galactic and Giant Molecula…

On the Observed Diversity of Star Formation Efficiencies in Giant Molecular Clouds

Kearn Grisdale, Oscar Agertz, Florent Renaud +3

Observations find a median star formation efficiency per free-fall time in Milky Way Giant Molecular Clouds (GMCs) on the order of with dispersions of $\sim0.5…

Physical properties and scaling relations of molecular clouds: the effect of stellar feedback

Kearn Grisdale, Oscar Agertz, Florent Renaud +1

Using hydrodynamical simulations of entire galactic discs similar to the Milky Way, reaching 4.6pc resolution, we study the origins of observed physical properties of giant molecul…

The impact of stellar feedback on the density and velocity structure of the interstellar medium

Kearn Grisdale, Oscar Agertz, Alessandro B. Romeo +2

We study the impact of stellar feedback in shaping the density and velocity structure of neutral hydrogen (HI) in disc galaxies. For our analysis, we carry out pc resolut…

Characterizing gravitational instability in turbulent multi-component galactic discs

Oscar Agertz, Alessandro B. Romeo, Kearn Grisdale

Gravitational instabilities play an important role in galaxy evolution and in shaping the interstellar medium (ISM). The ISM is observed to be highly turbulent, meaning that observ…
