Infall and Outflow Towards High-mass Starless Clump Candidates

T. G. S. Pillai, J. S. Urquhart, S. Leurini +6

The evolutionary sequence for high-mass star formation starts with massive starless clumps that go on to form protostellar, young stellar objects and then compact HII regions. Whil…

Detecting and Characterizing Mg II absorption in DESI Survey Validation Quasar Spectra

Lucas Napolitano, Agnesh Pandey, Adam D. Myers +33

We present findings of the detection of Magnesium II (Mg II, λ = 2796, 2803 Å) absorbers from the early data release of the Dark Energy Spectroscopic Instrument (DESI). DESI is pro…

Lopsided Satellite Distributions around Isolated Host Galaxies in a LCDM Universe

Adam Samuels, Tereasa G. Brainerd

A recent observational study found that the projected spatial distributions of the satellites of bright, isolated host galaxies tend to be lopsided with respect to the locations of…

Uncovering the geometry of the hot X-ray corona in the Seyfert galaxy NGC4151 with IXPE

V. E. Gianolli, D. E. Kim, S. Bianchi +106

We present an X-ray spectro-polarimetric analysis of the bright Seyfert galaxy NGC4151. The source has been observed with the Imaging X-ray Polarimetry Explorer (IXPE) for 700 ks,…

The SQUALO project (Star formation in QUiescent And Luminous Objects) I: clump-fed accretion mechanism in high-mass star-forming objects

A. Traficante, B. M. Jones, A. Avison +10

The formation mechanism of the most massive stars is far from completely understood. It is still unclear if the formation is core-fed or clump-fed, i.e. if the process is an extens…

The Eighteenth Data Release of the Sloan Digital Sky Surveys: Targeting and First Spectra from SDSS-V

Andrés Almeida, Scott F. Anderson, Maria Argudo-Fernández +151

The eighteenth data release of the Sloan Digital Sky Surveys (SDSS) is the first one for SDSS-V, the fifth generation of the survey. SDSS-V comprises three primary scientific progr…
