A wealth of observations have long suggested that the vast majority of
isolated classical dwarf galaxies (Mââ=107-109 Mââ) are currently
star-forming. However, recent observations of the large abundance of
"Ultra-Diffuse Galaxies" beyond the reach of previous large spectroscopic
surveys suggest that our understanding of the dwarf galaxy population may be
incomplete. Here we report the serendipitous discovery of an isolated quiescent
dwarf galaxy in the nearby Universe, which was imaged as part of the PEARLS GTO
program. Remarkably, individual red-giant branch stars are visible in this
near-IR imaging, suggesting a distance of 31 Mpc, and a wealth of archival
photometry point to an sSFR of 2Ă10â12 yrâ1. Spectra obtained
with the Lowell Discovery Telescope find a recessional velocity consistent with
the Hubble Flow and >1500 km/s separated from the nearest massive galaxy in
SDSS, suggesting that this galaxy was either quenched from internal mechanisms
or had a very high-velocity interaction with a nearby massive galaxy in the
past. This analysis highlights the possibility that many nearby quiescent dwarf
galaxies are waiting to be discovered and that JWST has the potential to
identify them.Comment: Submitted to ApJ Letters. Comments welcome
A wealth of observations have long suggested that the vast majority of isolated classical dwarf galaxies (M* = 107â109Mâ) are currently star forming. However, recent observations of the large abundance of "ultra-diffuse galaxies" beyond the reach of previous large spectroscopic surveys suggest that our understanding of the dwarf galaxy population may be incomplete. Here we report the serendipitous discovery of an isolated quiescent dwarf galaxy in the nearby Universe, which was imaged as part of the JWST PEARLS Guaranteed Time Observation program. Remarkably, individual red-giant branch stars are visible in this near-IR imaging, suggesting a distance of 30 ± 4 Mpc, and a wealth of archival photometry point to an sSFR of 2 Ă 10â11 yrâ1 and star formation rate of 4 Ă 10â4Mâ yrâ1. Spectra obtained with the Lowell Discovery Telescope find a recessional velocity consistent with the Hubble Flow and >1500 km sâ1 separated from the nearest massive galaxy in Sloan Digital Sky Survey suggesting that this galaxy was either quenched from internal mechanisms or had a very high-velocity (âł1000 km sâ1) interaction with a nearby massive galaxy in the past. This analysis highlights the possibility that many nearby quiescent dwarf galaxies are waiting to be discovered and that JWST has the potential to resolve them.T.M.C. is grateful for support from the Beus Center for Cosmic Foundations.

Introduction: Congenital prepubic sinuses are rare congenital anomalies of the urogenital tract with a varied presentation, but pain is an uncommon presenting symptom. Case presentation: This report describes a 14-year-old male who presented to the emergency department following five days of intermittent pain associated with a small opening superior to the base of the dorsum of the penis and superficial to the pubic symphysis. Surgical excision of the sinus tract revealed the sinus coursed towards the pubis and did not connect to the bladder. The histology of the tract revealed transitional epithelium surrounded by smooth muscle. Conclusion: Management of congenital prepubic sinuses relies upon prompt recognition, diagnosis, and surgical intervention to prevent complications
This is a continuing IPRO with the overall aim of improving and enhancing the image of Illinois Institute of Technology, both as an institution and a physical campus, in regards to sustainability and âgreenâ practices. To that end, the current semester is focused on several design projects based on concepts generated in the previous semesters along with input from the current semester to enhance a new âgreenâ campus. We will also be providing information on how IIT is currently acting in a sustainable fashion and how students on campus can contribute to our image as a sustainable campusDeliverable
