Data downloaded via parachute from a NASA super-pressure balloon
Ellen L. Sirks, Richard Massey, Ajay S. Gill +40
In April to May 2023, the superBIT telescope was lifted to the Earth's stratosphere by a helium-filled super-pressure balloon, to acquire astronomical imaging from above (99.5% of)…
A full reconstruction of two galaxy clusters intra-cluster medium with strong gravitational lensing
Joseph F. V. Allingham, Céline Bœhm, Dominique Eckert +6
Whilst X-rays and Sunyaev-Zel'dovich observations allow to study the properties of the intra-cluster medium (ICM) of galaxy clusters, their gravitational potential may be constrain…
Self-consistent Combined HST, K-band, and Spitzer Photometric Catalogs of the BUFFALO Survey Fields
Amanda Pagul, F. Javier Sánchez, Iary Davidzon +12
This manuscript presents new astronomical source catalogs using data from the BUFFALO Survey. These catalogs contain detailed information for over 100,000 astronomical sources in t…
Beyond the Ultra-deep Frontier Fields And Legacy Observations (BUFFALO): a high-resolution strong + weak-lensing view of Abell 370
Anna Niemiec, Mathilde Jauzac, Dominique Eckert +17
The HST treasury program BUFFALO provides extended wide-field imaging of the six Hubble Frontier Fields galaxy clusters. Here we present the combined strong and weak-lensing analys…
Lensing in the Blue II: Estimating the Sensitivity of Stratospheric Balloons to Weak Gravitational Lensing
Jacqueline E. McCleary, Spencer W. Everett, Mohamed M. Shaaban +23
The Superpressure Balloon-borne Imaging Telescope (SuperBIT) is a diffraction-limited, wide-field, 0.5 m, near-infrared to near-ultraviolet observatory designed to exploit the stra…
The Magnificent Five Images of Supernova Refsdal: Time Delay and Magnification Measurements
Patrick L. Kelly, Steven Rodney, Tommaso Treu +28
In late 2014, four images of Supernova (SN) "Refsdal," the first known example of a strongly lensed SN with multiple resolved images, were detected in the MACS J1149 galaxy-cluster…
Constraints on the Hubble constant from Supernova Refsdal's reappearance
Patrick L. Kelly, Steven Rodney, Tommaso Treu +27
The gravitationally lensed Supernova Refsdal appeared in multiple images, produced through gravitational lensing by a massive foreground galaxy cluster. After the supernova appeare…
BUFFALO/Flashlights: Constraints on the abundance of lensed supergiant stars in the Spock galaxy at redshift 1
Jose M. Diego, Sung Kei Li, Ashish K. Meena +27
We present a constraint on the abundance of supergiant (SG) stars at redshift z approx. 1, based on recent observations of a strongly lensed arc at this redshift. First we derive a…
RXJ0437+00: Constraining Dark Matter with Exotic Gravitational Lenses
David J. Lagattuta, Johan Richard, Harald Ebeling +6
We present the first strong-gravitational-lensing analysis of the galaxy cluster RXJ0437.1+0043 (RXJ0437; z = 0.285). Newly obtained, deep MUSE observations, Keck/MOSFIRE near-infr…
ALMA Lensing Cluster Survey: Deep 1.2 mm Number Counts and Infrared Luminosity Functions at
Seiji Fujimoto, Kotaro Kohno, Masami Ouchi +40
We present a statistical study of 180 dust continuum sources identified in 33 massive cluster fields by the ALMA Lensing Cluster Survey (ALCS) over a total of 133 arcmin area…
On the correlation between dark matter, intracluster light and globular cluster distribution in SMACS0723
J. M. Diego, M. Pascale, B. Frye +9
We present a free-form model of SMACS0723, the first cluster observed with JWST. This model makes no strong assumptions about the distribution of mass (mostly dark matter) in the c…
A new step forward in realistic cluster lens mass modelling: Analysis of Hubble Frontier Field Cluster Abell S1063 from joint lensing, X-ray and galaxy kinematics data
Benjamin Beauchesne, Benjamin Clément, Pascale Hibon +14
We present a new method to simultaneously/self-consistently model the mass distribution of galaxy clusters that combines constraints from strong lensing features, X-ray emission an…
Strong gravitational lensing's 'external shear' is not shear
Amy Etherington, James W. Nightingale, Richard Massey +19
The distribution of mass in galaxy-scale strong gravitational lenses is often modelled as an elliptical power law plus 'external shear', which notionally accounts for neighbouring…
