Observation of the Halo of NGC 3077 Near the "Garland" Region Using the Hubble Space Telescope [PDF]

open access: yes, 2001
We report the detection of upper main sequence stars and red giant branch stars in the halo of an amorphous galaxy, NGC3077. The observations were made using Wide Field Planetary Camera~2 on board the Hubble Space Telescope.

The Tip of the Red Giant Branch Distance to the Large Magellanic Cloud [PDF]

open access: yesThe Astronomical Journal, 2000
We present the I-band luminosity function of the red giant branch stars in the Large Magellanic Cloud (LMC) using the data from the Magellanic Clouds Photometric Survey (Zaritsky, Harris & Thompson, 1997). Selecting stars in uncrowded, low-extinction regions, a discontinuity in the luminosity function is observed at I_0 = 14.54 mag.

Synapsids and sensitivity: Broad survey of tetrapod trigeminal canal morphology supports an evolutionary trend of increasing facial tactile specialization in the mammal lineage

open access: yesThe Anatomical Record, EarlyView.
Abstract The trigeminus nerve (cranial nerve V) is a large and significant conduit of sensory information from the face to the brain, with its three branches extending over the head to innervate a wide variety of integumentary sensory receptors, primarily tactile.

The Stellar Populations of the Carina Dwarf Spheroidal Galaxy: I. a New Color-Magnitude Diagram for the Giant and Horizontal Branches

open access: yes, 1994
We report on the first in a series of studies of the Carina dwarf spheroidal galaxy, a nearby satellite of our Galaxy. Our two major results are: 1) precise BI photometry ($\sigma_{B-I} \simlt 0.05$ for $V \simlt 22$) for 11,489 stars in the Carina field,

Locating Traces of Arboreal Beings: Connecting the Tree and the Woodblock

open access: yesArchaeology in Oceania, EarlyView.
ABSTRACT Woodblocks for printmaking are multi‐perspectival communicators inscribed with layered narratives. The artistic process of cutting excavates the surface of a woodblock, making visible lesser‐seen traces of the past, reflective of the practice of archaeology.

Clinical periodontal diagnosis

open access: yesPeriodontology 2000, EarlyView., 2023
Abstract Periodontal diseases include pathological conditions elicited by the presence of bacterial biofilms leading to a host response. In the diagnostic process, clinical signs such as bleeding on probing, development of periodontal pockets and gingival recessions, furcation involvement and presence of radiographic bone loss should be assessed prior ...

Asteroseismology Sheds Light on the Origin of Carbon-deficient Red Giants: Likely Merger Products and Linked to the Li-rich Giants

open access: yesThe Astrophysical Journal, 2023
Carbon-deficient red giants (CDGs) are a peculiar class of stars that have eluded explanation for decades. We aim to better characterize CDGs by using asteroseismology (Kepler, TESS) combined with spectroscopy (APOGEE, LAMOST), and astrometry (Gaia).

A photometric and spectroscopic study of the new dwarf spheroidal galaxy in Hercules

open access: yes, 2009
Our aim is to provide as clean and as complete a sample as possible of red giant branch stars that are members of the Hercules dSph galaxy. With this sample we explore the velocity dispersion and the metallicity of the system.

A New Color-Magnitude Diagram for Palomar 11 [PDF]

open access: yes, 2006
We present new photometry for the Galactic thick disk globular cluster Palomar 11 extending well past the main sequence turn-off in the V and I bands. This photometry shows noticeable red giant and subgiant branches.

Reddening and Distance of the Local Group Starburst Galaxy IC 10

open access: yes, 2009
We estimate the reddening and distance of the nearest starburst galaxy IC 10 using deep near infrared $JHK_{S}$ photometry obtained with the Multi-Object InfraRed Camera and Spectrograph (MOIRCS) on the Subaru telescope.
