Detection of a dark matter subhalo in the strongly lensed system PJ011646

Aristeidis Amvrosiadis, James W. Nightingale, Qiuhan He +12

We present a strong lensing analysis of the system PJ011646 using high-resolution (0.1 arcsec) Atacama Large Millimeter/submillimeter Array (ALMA) dust-continuum observations…

Revealing the nature of the starburst galaxies in the overdensity HATLAS J0849

Melanie Kaasinen, Francesca Rizzo, Francesco Valentino +4

Today's most massive ellipticals are proposed to originate from starbursting galaxies in overdensities. To discern what triggers these starbursts, and their desce…

Measuring the Stellar-to-Halo Mass Relation at Solar masses, using forthcoming space-based imaging of galaxy-galaxy strong lenses

Kaihao Wang, Xiaoyue Cao, Ran Li +11

The stellar-to-halo mass relation (SHMR) is central to understanding the co-evolution of galaxies and their host dark matter haloes, yet it remains weakly constrained for dwarf gal…

Probing Dark Matter Substructures with Free-Form Modelling: A Case Study of the `Jackpot' Strong Lens

Xiaoyue Cao, Ran Li, James W. Nightingale +12

Characterising the population and internal structure of sub-galactic halos is critical for constraining the nature of dark matter. These halos can be detected near galaxies that ac…

Detailed lens modeling and kinematics of the submillimeter galaxy G09v1.97. An analysis of CO, H2O, H2O+, and dust continuum emission

K. Kade, C. Yang, M. Yttergren +14

The formation mechanisms of intensely starbursting galaxies at high redshift remain unknown. One possible mechanism for triggering these starbursts is mergers and interactions, but…

Hiding behind a curtain of dust: Gas and dust properties of an ultra-luminous strongly-lensed z = 3.75 galaxy behind the Milky Way disk

Belén Alcalde Pampliega, Kevin C. Harrington, Aristeidis Amvrosiadis +21

We present a detailed analysis of J154506, a strongly lensed submillimeter galaxy behind the Lupus-I molecular cloud, and characterisation of its physical properties using a combin…
