Cold atomic hydrogen in the inner galaxy

The VLA is used to measure 21 cm absorption in directions with the absolute value of b less than 1 deg., the absolute value of 1 less than 25 deg. to probe the cool atomic gas in the inner galaxy. Abundant H I absorption is detected; typical lines are deep and narrow, sometimes blending in velocity with adjacent features. Unlike 21 cm emission not all allowed velocities are covered: large portions of the l-v diagram are optically thin. Although not similar to H I emission, the absorption shows a striking correspondence with CO emission in the inner galaxy: essentially every strong feature detected in one survey is seen in the other. The provisional conclusion is that in the inner galaxy most cool atomic gas is associated with molecular cloud complexes. There are few or no cold atomic clouds devoid of molecules in the inner galaxy, although these are common in the outer galaxy

Letter from A[nna] R. Dickey to John Muir, [1912 ?] Aug 10.

[1]Dear Mr Muir,I am so glad you had so lovely a motor trip. I have had six rather lonely weeks with all good friends away but Ellie flitted in this week bringing cheer and much doings. I am sorry I had planned going north just as Mrs Hooker comes on a visit too but all plans are made for spending Wednesday, Thursday & Friday of next week at Hotel Stewart S. F. and then05246 [2]going on to Mendocino Co. where Donald is if I can be accommodated. If not I may follow your suggestion and try a cabin in Muir Woods. The name sounds inviting. the heat has been intense lately I shall be glad of a whiff of the sea near the Golden Gate and a glimpse of S. F. since the earthquake. When I am settled I shall answer your good welcome letter in decent fashion. Meanwhile, affectionate regardsA. R. DickeyAugust 10t

[1][letterhead]SAN FRANCISCO, CAL. March 29 1903Dear Mr Muir,I am spending a week in the city with my roommate at school, a true scotch woman, Miss McIntyre, and should like to bring her with me to call upon you some day at your home, providing you are not too busy to receive visitors.We have been in Los Angeles and spent some days in the Hooker home with Ellie Mosgrove, and together we talked over trails past and 03199[2][illegible]future. We were greatly amused at the judge\u27s article in [Sunset?]. He did give you credit for being of the party but the chief figure of course was His Lordship.Donald and I are going home to the Mississippi valley for our summer vacation so we shall have none of the glories of the summer feast, for which we were so indebted to you, but we hope to view the wonders of the Yellowstone Park en route.I shall be very glad of an opportunity of selling you once more but if a call would03199 [3][letterhead]inconvenience you in the least this week, please let me know with all scotch honesty—Very sincerely yoursAnna R. Dickey.0319

Letter from Anna R. Dickey to John Muir, [ca. 1913] Aug 1.

[1]Dear Mr Muir,I cannot tell you how much I appreciated seeing you in S.F.- and the memory of our little visit and delightful lunch has lingered with us into these lonly woods. we are perfectly delighted with Arbolado - the stage ride is very fine. there are lovely waterfalls to visit and new trails awaiting us each day, treats seem inexhuastible The delightful party we formed here is breaking up now I\u27m sorry to say. several friends of Mrs Hookers: Eellie - but Miss Roberts still remains.The table is splendid and we long to have you here and fill out those cheeks. If the Parsons come home do turn over Hetch-Hetchy to them or Mr Colby and come over for a trail for the sake of Auld lang syne!Miss Heal is reveling in your Mountains of California and feels as though she was communing with your woods spirit every day05506 [2]I am not so easily satisfied, and should like the author in person - we shall remain until about the 14th, and then stop a few days at Pine Inn - Carmel. Donald leaves Dubuque today for New Brunswick. He has had fearful heat at Mothers - I\u27m glad I waited for a cooler season-With warmest regards from your friends-in-the-woodsAnna R.

Letter from Anna R. Dickey to John Muir, [ca. 1913 Oct].

Mrs Dickey[1][letterhead]Dear Mr Muir,I am making a flying visit to Mother as I am sailing on the Adriatic on Saturday for Naples to be the guest of Mrs Fowler in Italy and Algiers - hoping to go on the desert All of this is very sudden I have declined two previous invitations but Thursday Donald came out of the New Brunswick woods looking splendidly after his three blessed months05564 [2]and he persuaded me to accept and promises me to come over by New Years if he can finish up his photo work & be released from a certain contract. I hope I am doing right but it is a great temptation as I do not know when I could ever go otherwise, I am so in hopes of making connections with the Hookers but have only their Paris bankers\u27 address and have written them there to forward. I get homesick twinges for the dear home and California. you must send a line sometime. My address is c/o Mrs. E. M. Fowler. Broom Shipley & Co. London, England.I spent a week in Washington, had a nice little visit over the telephone with Mr Merriam. He was away until the last day. I so sincerely hope you are well and that the coming year may bring you every joy and comfort.Ever sincerely your friendAnna R. DickeySunday.On limited between Chicago & N.Y

HI Emission and Absorption in the Southern Galactic Plane Survey

We present preliminary results from the Southern Galactic Plane Survey (SGPS) Test Region and Parkes data. As part of the pilot project for the Southern Galactic Plane Survey, observations of a Test Region (325.5 deg < l < 333.5 deg; -0.5 deg < b < 3.5 deg) were completed in December 1998. Single dish observations of the full survey region (253 deg < l < 358 deg; |b| <1 deg) with the Parkes Radio Telescope were completed in March 2000. We present a sample of SGPS HI data with particular attention to the smallest and largest scale structures seen in absorption and emission, respectively. On the large scale, we detect many prominent HI shells. On the small scale, we note extremely compact, cold clouds seen in HI self-absorption. We explore how these two classes of objects probe opposite ends of the HI spatial power spectrum.Comment: 9 pages, 3 embedded postscript & 4 jpeg figures.

A Complete Atlas of HI Absorption toward HII Regions in the Southern Galactic Plane Survey (SGPS1)

We present a complete catalog of H I emission and absorption spectrum pairs, toward H II regions, detectable within the boundaries of the Southern Galactic Plane Survey (SGPS I), a total of 252 regions. The catalog is presented in graphical, numerical and summary formats. We demonstrate an application of this new dataset through an investigation of the locus of the Near 3kpc Arm.Comment: Accepted for publication by ApJS Feb 6, 2014.
