MUSE-ALMA Haloes XV: Cold molecular, ionised, and stellar kinematics of HI-rich galaxies at z 0.5

C. Barfety, N. M. Förster Schreiber, C. Péroux +13

Spatially resolved galaxy kinematics are well studied at z 0 and z > 1, revealing that disks are common out to z , albeit with higher velocity dispersions. z …

Slow stellar halo rotation as a signature of disc flips and GES-like mergers

Kirill Batrakov, Alis J. Deason, Francesca Fragkoudi +3

The stellar halo of the Milky Way (MW) exhibits a weak net prograde rotational signal ( km~s), yet its origin remains unexplained. To investigate this, we u…

Impact of 21-cm foreground mitigation strategies on reionization power spectrum constraints

Sambit K. Giri, Florent Mertens

The 21-cm signal probes the intergalactic medium during the Epoch of Reionization (EoR) but is overwhelmed by astrophysical foregrounds orders of magnitude stronger than the cosmol…

Constraints on Late-Time Flaring from Luminous Fast Blue Optical Transients using the Transiting Exoplanet Survey Satellite and the Zwicky Transient Facility

Rahul Jayaraman, Anna Y. Q. Ho, Michael M. Fausnaugh +14

The Luminous Fast Blue Optical Transient (LFBOT) AT2022tsd exhibited minutes-timescale optical flares in the tens of days following the initial transient event, likely due to a cen…
