PSR J1841-0500: a radio pulsar that mostly is not there

F. Camilo, S. M. Ransom, S. Chatterjee +2

In a search for radio pulsations from the magnetar 1E 1841-045, we have discovered the unrelated pulsar J1841-0500, with rotation period P=0.9 s and characteristic age 0.4 Myr. One…

Fullerenes in circumstellar and interstellar environments

Jan Cami, Jeronimo Bernard-Salas, Els Peeters +1

We recently identified several emission bands in the Spitzer-IRS spectrum of the unusual planetary nebula Tc 1 with the infrared active vibrational modes of the neutral fullerene s…

The Magnetic Field in Taurus Probed by Infrared Polarization

Nicholas L. Chapman, Paul F. Goldsmith, Jorge L. Pineda +3

We present maps of the plane-of-sky magnetic field within two regions of the Taurus molecular cloud: one in the dense core L1495/B213 filament, the other in a diffuse region to the…

Minimum Requirements for Detecting a Stochastic Gravitational Wave Background Using Pulsars

J. M. Cordes, R. M. Shannon

We assess the detectability of a nanohertz gravitational wave (GW) background with respect to additive red and white noise in the timing of millisecond pulsars. We develop detectio…

On the Formation of CO2 and Other Interstellar Ices

Robin T. Garrod, Tyler Pauly

We investigate the formation and evolution of interstellar dust-grain ices under dark-cloud conditions, with a particular emphasis on CO2. We use a three-phase model (gas/surface/m…

Formation of Massive Black Holes in Dense Star Clusters. II. IMF and Primordial Mass Segregation

Sanghamitra Goswami, Stefan Umbreit, Matt Bierbaum +1

A promising mechanism to form intermediate-mass black holes (IMBHs) is the runaway merger in dense star clusters, where main-sequence stars collide and form a very massive star (VM…

An Arecibo Search for Pulsars and Transient Sources in M33

N. D. R. Bhat, J. M. Cordes, P. J. Cox +4

We report on a systematic and sensitive search for pulsars and transient sources in the nearby spiral galaxy M33, conducted at 1.4 GHz with the Arecibo telescope's seven-beam recei…

The GALFA-HI Survey: Data Release 1

J. E. G. Peek, Carl Heiles, Kevin A. Douglas +10

We present the Galactic Arecibo L-Band Feed Array HI (GALFA-HI) survey, and its first full data release (DR1). GALFA-HI is a high resolution (~ 4'), large area (13000 deg^2), high…
