Spitzer observations of extended Lyman-alpha Clouds in the SSA22 field

open access: yes, 2008
We present the results of a Spitzer IRAC and MIPS 24 micron study of extended Lyman-alpha clouds (or Lyman-alpha Blobs, LABs) within the SSA22 filamentary structure at z = 3.09.

Discovery of a Very Highly Extinguished Supernova in a Luminous Infrared Galaxy [PDF]

open access: yes, 2008
We report the discovery of a confirmed supernova (SN) and a supernova candidate in near-infrared images from the ALTAIR/NIRI adaptive optics system on the Gemini-North Telescope and NICMOS on the Hubble Space Telescope. The Gemini images were obtained as

JWST Imaging of the Closest Globular Clusters—V. The White Dwarfs Cooling Sequence of M4

open access: yesAstronomische Nachrichten, Volume 346, Issue 2, February 2025.
ABSTRACT We combine infrared (IR) observations collected by the James Webb Space Telescope with optical deep images by the Hubble Space Telescope taken ~20 years earlier to compute proper‐motion membership for the globular cluster (GC) M4 (NGC 6121) along its entire white dwarf (WD) cooling sequence (CS).

PEARLS: Discovery of Point-source Features within Galaxies in the North Ecliptic Pole Time Domain Field

open access: yesThe Astrophysical Journal
The first public 0.9–4.4 μ m NIRCam images of the North Ecliptic Pole Time Domain Field uncovered galaxies displaying point-source features in their cores as seen in the longer-wavelength filters. We visually identified a sample of 66 galaxies (∼1 galaxy

A population of luminous accreting black holes with hidden mergers

open access: yes, 2018
Major galaxy mergers are thought to play an important part in fuelling the growth of supermassive black holes. However, observational support for this hypothesis is mixed, with some studies showing a correlation between merging galaxies and luminous ...

GALAXY-WIDE SHOCKS IN LATE-MERGER STAGE LUMINOUS INFRARED GALAXIES [PDF]

open access: yesThe Astrophysical Journal, 2011
We present an integral field spectroscopic study of two nearby Luminous Infrared Galaxies (LIRGs) that exhibit evidence of widespread shock excitation induced by ongoing merger activity, IC 1623 and NGC 3256. We show the importance of carefully separating excitation due to shocks vs.

Accretion Onto Weakly Magnetized Neutron Stars: Polarization Theory and Its Application to X‐Ray Burster GX 13+1

open access: yesAstronomische Nachrichten, Volume 346, Issue 1, January 2025.
ABSTRACT Observations show that the x‐ray emission of the accreting weakly magnetized neutron stars (WMNSs) is polarized. In this article, we summarize the analytical models for the polarized emission of various components of the WMNSs. We introduce a missing theoretical model, where we assume the emission comes from the spreading layer, the extension ...

Infrared composition of the Large Magellanic Cloud [PDF]

open access: yes, 2012
The evolution of galaxies and the history of star formation in the Universe are among the most important topics in today's astrophysics. Especially, the role of small, irregular galaxies in the star-formation history of the Universe is not yet clear ...
